Ammonium Metatungstate Powder Applied for Thermal Insulation Film

Ammonium metatungstate powder can be used as a raw material for preparing an alkali metal cation-co-doped tungsten oxide material, namely cesium tungsten bronze nanoparticles. And the obtained functional particles can be used for producing a transparent heat insulating material - building glass thermal insulation film.

According to experts, the new type of transparent heat insulation material of nano particle size of cesium tungsten bronze can be used to produce a transparent heat insulating film by a simple low temperature coating process at low cost. And such material can meet the requirements of high visible light transmittance, high heat insulation performance and high stability. Also, the transparent thermal insulation material has the advantages: the plasma wavelength range is between 800-1000nm. And since cesium tungsten bronze nanoparticles has good conductivity and no absorption in the visible light range, the obtained heat insulating material often has the characteristics of high transparency and high heat insulation effect.
