Cesium tungstate, such as Cs0.33WO3 nanopowder, is a kind of semiconductor material that can be used for preparing transparent heat-insulation coating. And the prepared coating is more and more widely applied in buildings and automobiles to achieve the purpose of heat shielding, energy reduction and environmental protection. According to the experts, the thermal insulation coating film formed by such a functional coating of Cs0.33WO3 on architectural glass is the result of the combined effect of absorption and reflection.

Cesium tungstate, which has the best infrared shielding feature, is mainly applied for manufacturing heat shielding material. And these heat insulation products are widely applied in buildings and automobiles. Wherein, the cesium tungstate used is cesium tungstate nanopowder, which can be synthesized by a high-temperature carbothermal reduction method. And the prepared Cs0.33WO3 particles are smaller with better crystallinity. Among them, the optimum synthesis conditions are 700 °C and 5 hours.

Cesium tungstate for production of new energy saving glass is cesium tungstate (Cs0.33WO3) nanopowder that has very strong absorption in the near-infrared wave band (800-1200nm of wavelength) and in the ultraviolet wave band (180-380nm of wavelength). Also, cesium tungstate nanoparticles have high transmittance in the visible wave band (380-800nm of wavelength).

Cesium tungstate for producing heat insulation window glass is cesium tungstate nanopowder - a near-infrared absorbing material that can exert excellent heat shielding function. Also, cesium tungstate nano powder is an anti-ultraviolet material that can shield most of the ultraviolet radiation.
