Cesium doped tungsten oxide is a type of dark blue nanopowder that may be used to prepare transparent nano-ceramic dispersion solution. As you may have known, heat insulation material, especially environmentally friendly heat-insulating material, is more and more popular. Therefore, with the popularization of this kind of dispersion solution in ceramics and other fields, the preparation of nano cesium doped tungsten oxide powder is more important. In this regard, some experts have proposed a preparation method of Cs doped tungsten oxide powder, including the following steps:

1.0 Weigh 7.6g ammonium paratungstate, 3.25g cesium hydroxide and 17.5g EDTA, add 50ml of ethylene 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 270°C for 5h;
3.0 The reactant obtained in the step 2.0 was subjected to alcohol washing, centrifugation, and vacuum drying at 80°C to obtain cesium doped tungsten oxide nano powder with complete crystallinity.
