Cesium doped tungsten oxide may be applied for preparing nano-ceramic color master, which is a type of environmentally friendly color master. Among them, the Cs doped tungsten oxide powder used is nano powder, and the obtained color master has excellent dispersibility and stability. Also, such color master has high hardness, high heat insulation and other good properties.

Therefore, the application of Cs doped tungsten oxide nanopowder is also being promoted, and therefore, the preparation of Cs doped tungsten oxide powder is more important. In this regard, experts have proposed a preparation method of Cs doped tungsten oxide powder, including the following steps:
1.0 Weigh 3.1g ammonium metatungstate, 0.83g cesium hydroxide and 5.1g tartaric acid, add 50ml propylene glycol, and react at 170°C for 3h;
2.0 The mixture obtained in step 1.0 is charged into a para-polyphenyl pressure reactor and reacted at 260°C for 8h;
3.0 The reactant obtained in the step 2.0 is subjected to alcohol washing, centrifugation, and vacuum drying at 80°C to obtain Cs doped tungsten oxide powder with complete crystallinity.
