In recent years, heat insulation products such as ATO, ITO, and Cs doped tungsten oxide have become more and more popular. Among them, Cs doped tungsten oxide has received more attention due to its superior thermal insulation property. Therefore, its preparation becomes more and more important. For this reason, experts have proposed a preparation method of Cs doped tungsten oxide powder, which includes the following steps:

Step one: Weigh 5.07g of ammonium tungstate, 1.95g of cesium nitrate and 14.6g of EDTA, add 50ml of ethylene glycol, and react at 170°C for 3h;

Step two: the mixture obtained in the step one is charged into a para-polyphenylene pressure capacity bomb, and reacted at 270°C for 5h;

Step three: the reactant obtained in the step two is subjected to alcohol washing, centrifugation, and vacuum drying at 80°C to obtain Cs doped tungsten oxide powder with complete crystallinity.
