Lead-based ceramics have been extensively studied because of their superior electrical properties and thermal stability. However, a major challenge for PYN-PHT-based ceramics is their high sintering temperature, which typically exceeds 1200 °C. At such elevated temperatures, severe lead volatilization occurs, resulting in deviations from the ideal stoichiometric ratio and subsequent degradation of electrical performance. To address this issue, sintering aids were introduced, effectively reducing the sintering temperature from 1175 °C to 1075 °C. This approach not only significantly suppressed lead volatilization but also promoted ceramic densification, demonstrating high effectiveness. Specifically, the as-prepared PYN-PHT-0.8(Cu 2+ +Sb 5+ ) ceramics exhibited a high piezoelectric coefficient of up to 610 pC/N, whereas previous processes required temperatures close to 1200 °C. Furthermore, the prepared ceramics showed enhanced stability at high-temperatures. Overall, these findings provide a practical strategy for improving the durability, efficiency, and reliability of piezoelectric components operating under harsh service conditions.

Direct ink writing (DIW) offers a promising route for fabricating piezoelectric ceramics with complex architectures, yet the solid loading of ceramic inks plays a decisive role in balancing printability, densification, defect formation, and final electrical performance. In this work, 0.25Pb(Zn 1/3 Nb 2/3 )O 3 -0.75Pb 0.96 La 0.04 (Zr 0.53 Ti 0.47 )O 3 ceramics with 0.5 wt% Sb 2 O 5 addition were fabricated by DIW using inks with solid loadings of 74–79 wt%. The influence of solid loading on rheological behavior, debinding/sintering characteristics, microstructural evolution, and electrical properties was systematically investigated. All inks exhibited pronounced shear-thinning behavior, while increasing solid loading strengthened the particle network and improved shape retention. A TG/DTG-guided multistep debinding schedule was employed to suppress gas accumulation, cracking, and residual porosity during binder removal. With increasing solid loading from 74 to 77 wt%, enhanced particle packing, improved interlayer bonding, and promoted densification led to increased dielectric, ferroelectric, and piezoelectric responses. However, further increasing the solid loading to 78–79 wt% deteriorated ink flowability and induced agglomeration and interlayer defects, thereby hindering polarization switching and degrading electrical performance. The ceramic printed with 77 wt% solid loading exhibited the best overall properties, including a room-temperature relative permittivity of approximately 2.95 × 10 3 at 1 kHz, a piezoelectric coefficient d 33 of 491 pC/N, and a Curie temperature of approximately 212 °C. These results reveal the solid-loading-dependent rheology–defect–polarization relationship in DIW-printed PZN-PLZT-Sb ceramics and provide guidance for optimizing additively manufactured piezoelectric ceramic components.

Achieving superior energy storage in antiferroelectric ceramics is limited by a fundamental compromise: realxor behavior comes at the cost of sacrificing polarization strength. This directly leads to a mutually restrictive balance between recoverable energy density ( W rec ) and energy storage efficiency ( η ). To overcome this, we develop a Bi-induced local bonding modulation strategy in Pb 0.92-1.5 x Sr 0.08 Bi x Zr 0.49 Sn 0.5 Ti 0.01 O 3 ceramics that simultaneously strengthens the AFE framework and refines polarization response. This approach elevates both the breakdown strength and the AFE-FE transition field, allowing the material to withstand higher electric fields and release greater stored energy. The optimized composition achieves a record-high W rec of 15.6 J cm −3 with ∼90% efficiency under 600 kV cm −1 , alongside ultrafast discharge ( t 0.9 ∼64.5 ns) and excellent thermal/frequency stability. Atomic-scale characterization reveals a coexistence of robust long-range AFE order and local polar heterogeneity, which collectively smooths the field-induced transition path and suppresses early breakdown. This work provides a generalizable design principle for dielectric capacitors by strategically decoupling polarization enhancement from relaxor behavior, paving the way for high-energy, high-efficiency pulsed-power systems.

Mn O 2 -modified Pb 0 . 9 6 2 5 Sm 0 . 0 2 5 ( Mg 1 / 3 Nb 2 / 3 ) 0 . 7 1 Ti 0 . 2 9 O 3 ceramics were prepared via a solid-state reaction approach. Results of detailed characterizations revealed that the addition of Mn O 2 has influence on the grain size, and all samples exhibit a pure perovskite structure. As the content of manganese increases, the volume of tetragonal phase increases. The ceramics with 1.5 mol.% Mn O 2 show a high electro-strain of 0.151% at 2 kV/mm. Therefore, this study provides a new insight into the role of Mn O 2 addition in tailoring the electrical properties of the Sm-PMN-PT ceramics by acceptor doping.

A series of (100 − x ) Pb(Mg 1 / 3 Nb 2 / 3 ) O 3 − x PbTiO 3 (PMN − x PT, x = 24, 25, 26) ceramics were prepared by solid-state reaction technique using MgNb 2 O 6 precursor. The results of the detailed characterizations reveal that the content of PT has negligible influence on the grain size, and all samples possess the perovskite structure. As the PT content increases, the samples changed from the normal ferroelectric phase to the ergodic relaxor state at room temperature. As a result, PMN– x PT ceramics are endowed with electro-strain of 0.08% at a relatively low electric field of 2 kV/mm, and effective piezoelectric coefficient of 320 pm/V was obtained. Simultaneously, the PMN– x PT ceramics have exceptional pyroelectric performance, exhibiting a high pyroelectric coefficient p ∼ 5.5 – 6.3 × 10 − 8 C⋅cm − 2 ⋅K − 1 . This study demonstrates the great potential of PMN– x PT for piezoelectric and pyroelectric device applications.

Murals are one of the important cultural heritages of mankind. The microbial control of murals is an important subject in mural painting conservation. In recent years, electron beam radiation sterilization has attracted more and more attention in the field of cultural relic protection. Murals are immovable cultural relics, so conventional electron beam irradiation equipment can not be used. However, the development of small mobile electron beam irradiation equipment shows the potential of radiation’s application in the sterilization protection of immovable cultural relics such as murals. A feasibility study of radiation sterilization in mural paintings is needed to investigate the effect of sterilization and the influence of sterilization dose on the stability of mural painting pigments and bonding materials. In this paper, the radiation effects of typical bacteria in tomb murals and mineral pigment powder in ancient Chinese paintings were studied in a laboratory. Firstly,aeromonas hydrophila(Aer.h) andpenicillium flavigenum(PNC) were selected as representative strains to determine the appropriate sterilization dose for murals. Then, the effects of radiation on seven kinds of ancient Chinese mineral pigments and white calcium carbonate in the ground layer were verified. The results are as follows: the radiation dose of 10 kGy can effectively remove the two typical strains. This sterilization dose will cause a color difference in calcium carbonate and lead white, while other color pigments are essentially stable. Based on the color difference and UV-vis intensities of the four white carbonate samples, the color change in two of them increased with increasing the dose up to 30 kGy, after which signs of saturation began to appear. X-ray diffraction (XRD), Raman spectra, X-ray photoelectron spectroscopy (XPS) and X-ray absorption near edge structure (XANES) spectra showed that the chemical structure of the samples did not change after irradiation. The formation of free radicals in treated samples was confirmed using an electron paramagnetic resonance (EPR) spectrum test. According to all characterization results, the color difference between the four white carbonate samples may be due to the combination of unpaired electrons and defects in the process of electron beam irradiation to form color centers. After forming the color center, the light absorption of the four samples changed. This is a reversible change, but the samples will take a long time to return to their original state. This study focuses on the influence of electron beam radiation on pigment composition, which is a preliminary exploration of whether radiation sterilization can be applied to the protection of ancient Chinese mural paintings, and the experimental results can provide basic data for later application.Keywords:electron beam radiation;mural protection;radiation sterilization;mineral pigment;chromatic aberration

The fabrication method plays a key role in the performance of lead magnesium niobate–lead titanate-based ceramics. (1 −w)[Pb(Mg1/3Nb2/3)0.67Ti0.33O3]-w[Pb1−1.5xSmx(Mg1/3Nb2/3)yTi1−yO3] piezoelectric ceramics were prepared by sintering the mixture of two different crystalline phases in which two pre-sintered precursor powders were mixed and co-fired at designated ratios (w= 0.3, 0.4, 0.5, 0.6). The X-ray diffraction results show that all the ceramics presented a pure perovskite structure. The grains were closely packed and the average size was ~5.18 μm based on observations from scanning electron microscopy images, making the ceramics have a high density that is 97.8% of the theoretical one. The piezoelectric, dielectric, and ferroelectric properties of the ceramics were investigated systematically. It was found that the properties of the ceramics were significantly enhanced when compared to the ceramics fabricated using the conventional one-step approach. An outstanding piezoelectric coefficientd33of 1103 pC/N and relative dielectric permittivityε33/ε0of 9154 was achieved for the ceramics withw= 0.5.Keywords:two different crystalline phases;PMNT-PSMNT;piezoelectric properties;dielectric properties

Lead zirconate titanate-based piezoelectric ceramics (Pb 0·91 La 0·06 (Zr 0·58 Ti 0.42 ) 0.975 Nb 0·02 O 3 , PLZT) were prepared by water-soluble defatted powder injection molding using bismuth stearate as surfactant . The effects of bismuth stearate surfactant amount on the feed viscosity, water degreasing rate and electrical properties were studied. The results showed that the bismuth stearate coating reduces agglomeration between the PLZT powders and decreases the viscosity of the feed. During sintering, bismuth stearate is decomposed into bismuth oxide, which acts as sintering aid to increase the density of the sintered bismuth stearate-coated PLZT ceramics. Bi 3+ dissolves into the perovskite crystal lattice , which increases the tetragonality factor and the content of tetragonal phase, and improves the dielectric, ferroelectric and piezoelectric properties of the bismuth stearate-coated PLZT ceramics. This study provides a novel modification method for the production of injection molded ceramics using a water-soluble binder system.

High-entropy oxides with complex compositions can be designed as new ferroelectric materials with interesting physical consequences. Here, a series of high-entropy perovskite ceramics (Bi 0.2 Na 0.2 Ba 0.2 Sr 0.2 Ca 0.2 TiO 3 , Bi 0.2 Li 0.2 Ba 0.2 Sr 0.2 Pb 0.2 TiO 3 , Bi 0.2 Na 0.2 Ba 0.2 Sr 0.2 Pb 0.2 TiO 3 , Bi 0.2 K 0.2 Ba 0.2 Sr 0.2 Pb 0.2 TiO 3 , and Bi 0.2 Ag 0.2 Ba 0.2 Sr 0.2 Pb 0.2 TiO 3 ) was proposed, which selected various elements to diminish the formational enthalpy and thus to achieve a single-phase structure. Detailed crystal structure and microstructure characterizations indicated that the high-entropy perovskites exhibited a single tetragonal phase with excellent chemical homogeneity. The equiatomic ratios of the A-site cations in perovskites could be used to maximize the entropy stabilization effect and effectively disordered the symmetry of the crystal structure. A robust ferroelectric polarization reaching 20 μC/cm 2 under 50 kV/cm was achieved in Bi 0.2 Na 0.2 Ba 0.2 Sr 0.2 Pb 0.2 TiO 3 high-entropy ferroelectrics. This work provides an effortless approach to discover new high-entropy ferroelectrics in materials with unexplored compositional complexity and gives additional opportunities to design and tailor the functional properties in entropy-stabilized ferroelectrics.

Acrylic resin and PLZT (Pb0.910La0.060 (Zr0.580Ti0.420)0.975Nb0.020O3.000) powder were mixed to prepare PLZT/acrylic resin thermosetting feedstock. Injection molding is used to form high-strength PLZT piezoelectric ceramic embryos then sintered to piezoelectric materials. The experimental results showed that the residual polarization is higher at 85% solid content of the feed and the d33 value increased. And the PLZT powder coated with stearic acid can improve the piezoelectric and ferroelectric properties of powder injection molded piezoelectric ceramics. Tests above are intended to provide preliminary exploration for thermal curing injection molding and thermal curing 3 D printing piezoelectric ceramics.

For the first time, rare-earth phosphate compound Cs 4 PbTb 2 (PO 3 ) 12 was prepared using molten salt method and structurally characterized by single-crystal X-ray diffraction (XRD). Its structure features a three-dimensional (3D) open framework constructed by P 4 O 12 cyclotetraphosphate groups and (Pb|Tb)O 8 polyhedra, with large holes filling with Cs + ions. The P 4 O 12 groups in this structure are isolated and each P 4 O 12 is surrounded by four (Pb|Tb)O 8 polyhedra by sharing terminal O atoms. Furthermore, the powder XRD , infrared (IR) spectrum, Ultraviolet–visible (UV–Vis) spectroscopy and photoluminescence (PL) properties for title compound were studied. Under near-UV excitation (378 nm), the emission colour turns from green through yellow to pure red by simply adjusting the Eu 3+ concentration due to the efficient Tb 3+ →Eu 3+ energy transfer mechanism.

Lead sulfate is produced when a lead acid battery discharges, and it is also known that big PbSO 4 crystals are less active than the smaller ones because they dissolve slower, thus result in failure of the battery. However, little is known if chemically prepared PbSO 4 can be used as active material of lead acid batteries. Here, we report the preparation of PbSO 4 by facile chemical precipitation of aqueous lead acetate with sodium sulfate and its utilization as the positive active material. The results show that the PbSO 4 alone is not good enough for the purpose, but its mixtures with Pb 3 O 4 are as excellent as the industrial leady oxide. For example, the mixtures containing 5, 10, 20, and 30 wt.% of Pb 3 O 4 discharge 78.2, 92.9, 88.0, and 91.5 mAh g −1 at a current density of 100 mA g −1 , respectively. Also, the one with 10 % Pb 3 O 4 remains 93 % capacity in 150, 100 % DOD cycles.
