Study on the novel green magnetoplumbite-type oxide BaZn6-xNixTi6O19: synthesis, structure and properties

Magnetoplumbite-type oxides display various properties and find applications in multiple fields. In this study, a novel magnetoplumbite-type solid solution BaZn 6- x Ni x Ti 6 O 19 (0 ≤  x  ≤ 4) with vivid green color was synthesized through a high-temperature solid-phase method for the first time. The as-synthesized BaZn 6- x Ni x Ti 6 O 19 solid solution crystallizes in the space group of P6 3 / mmc . The solid solution exhibits excellent green property, and its color is adjustable with increasing doping levels of Ni 2+ . The depth of color originates from the content and position of Ni 2+ in the solid solution. BaZn 6- x Ni x Ti 6 O 19 is suitable for PMMA (Polymethyl methacrylate) pigment and hydrophobic coating. Colored PMMA containing BaZn 6- x Ni x Ti 6 O 19 exhibits vibrant colors with high saturation, showing excellent application potential. The hydrophobic coating compounded with BaZn 6- x Ni x Ti 6 O 19 exhibits near-superhydrophobic properties and demonstrates excellent self-cleaning effects under simulated natural environmental conditions.
