Synthesis of Nano-Crystalline Zr0.8Sn0.2TiO4 Powder by Choline-Chloride-Malonate Deep Eutectic Solvents

Abstract Chloride-malonate deep eutectic solvent (Cm-DES) was applied to synthesize nano-crystalline Zr0.8Sn0.2TiO4 ceramic powder by using Zr(CH3COO)4, SnCl2∙2H2O and Ti(OCH3CH3)4 as raw materials. The nano-crystalline Zr0.8Sn0.2TiO4 powder was obtained at 450 °C, dramatically lower than that by solid state reaction. Meantime, the grain size of as-synthesized Zr0.8Sn0.2TiO4 powder at 450 °C is 10.7 nm. In the synthesized process, Cm-DES, as a solvent and template, affects the synthesis process and the time required for synthesis is greatly reduced. These results show that the Cm-DES is suitable and prospective for the synthesis of nano-crystalline Zr0.8Sn0.2TiO4 ceramic powder, which could contribute to reduce energy consumption and time cost.
