Cesium tungstate powder may be used in the field of thermal insulating glass. With the promotion of nano grain size cesium tungstate in the field of thermal insulation, the preparation of cesium tungstate nanopowder is more important. In this regard, some experts have proposed to use tungsten chloride and cesium hydroxide as raw materials, dissolved in anhydrous ethanol, and reacted in an autoclave at 200°C for 12 hours. And the obtained precipitated product is further heat treated at 500-900°C in N2 atmosphere for 1h to obtain cesium tungstate powder.

Cesium tungstate powder may be applied for preparing heat insulation coating. And in order to reduce the particle size of cesium tungstate, some experts have proposed that use ammonium paratungstate and cesium formate as raw materials, and plasma as a heat source for rapid high temperature thermal decomposition solid phase reaction. Also, to improve the infrared absorption property of nano grain size cesium tungstate, hydrogen is added as the gas source.

Cesium tungstate powder may be used for the preparation of thermal insulation coating. According to experts, the obtained coating is an environmentally friendly coating material. And it has excellent near-infrared shielding effect and ultraviolet blocking effect, and does not affect the passage of visible light, so it has wide application in the construction industry. Due to its excellent thermal insulation and environmental protection properties, the application of cesium tungstate nanopowder is becoming more and more widespread, such as, glass curtain wall, glass vault, sun room glass, and so on.

Cesium tungstate powder may be used to prepare near-infrared shielding material. The prepared material is a new type of heat insulating material that is widely used in construction and automotive glass. With the promotion of its application, the raw material of thermal insulation material - cesium tungstate nano powder - has also received more and more attention. Therefore, experts pay more attention to the preparation of nano grain size cesium tungstate.
