Cesium Doped Tungsten Oxide Applied for Near Infrared Shielding Material

Cesium doped tungsten oxide may be applied for preparing near infrared shielding material, i.e. heat insulating material. Among them, the raw material Cs doped tungsten oxide powder is also generally called cesium tungstate or cesium tungsten bronze, which can reduce a large amount of infrared rays passing through the glass. According to experts, the heat insulation effect of Cs doped tungsten oxide powder is the best. While cesium tungstate is a non-integer metered valence state, the molecular formula cannot be accurately represented.

In addition, there are other well-known heat insulation materials, that is, ITO, ATO. ITO is generally used for conductive glass. Its heat insulation effect is good, and the transmittance is better than the other two. While the price is the most expensive. The transmittance of ATO is between ITO and cesium doped tungsten oxide materials. Its heat insulation is close to ITO, and the price is the lowest. However, experts say that the best near infrared shielding material is Cs doped tungsten oxide powder, followed by ITO and ATO.
