Study on the preparation of the CdS x Se1−x @ZrSiO4 red ceramic pigments and its properties

Abstract The color of the CdS x Se 1− x @ZrSiO 4 red ceramic pigment is associated with the condensed CdS x Se 1− x particles, which is incorporated into zirconium silicate microcrystals as a robust inclusion body. The pigments were prepared via the gel co-precipitation method. The as-prepared pigments were characterized by X-ray diffraction, CIE-L*a*b* color measurement, scanning electron microscopy, acoustic particle sizer, dynamic laser scattering particle size analysis and polarized optical microscopy, respectively. The results indicate that the pigments prepared in ethanolamine solution show a more intensive tinting capacity, superior thermal stability and the finer particle size than those prepared in prevailing pure water. The prepared red pigments can be potential applied as a promising ink material for inkjet printing. Graphical Abstract Diagram of acid picking pores on pigment encapsulation
