Tungsten trioxide is a type of transparent thermal insulation nanopowder that does not contain any impurities and satisfies the stoichiometric ratio strictly. It can be used for the production of automotive heat insulation film and building heat insulation film so that these places applied tungsten trioxide nanopowder in glass will have good shielding effect on near-infrared and ultraviolet rays.
Electrical Property of Tungsten Trioxide
Tungsten trioxide, which strictly meets the stoichiometric ratio and does not contain any impurities, is a kind of transparent insulator. The color and electrical property of non-stoichiometric WO3-y vary with the change of oxygen content. Since the oxygen content in tungsten oxide is difficult to control and the oxygen content largely determines the electrical properties of the material, it is more difficult to give specific electrical parameters of tungsten oxide such as carrier concentration, and mobility, etc. Thus, it often takes an approximation or hypothetical value in actual applications.
