Tungsten trioxide for manufacturing bathroom thermal insulating glass coating is a fine light yellow powder composed of tungsten trioxide particles under 100nm in diameter. Nano particle size tungsten trioxide has been the subject of attention from scholars and researchers across a variety of disciplines as this material is known for its faceted high surface area and its magnetic properties.

Tungsten trioxide, as an n-type semiconductor material, is often doped with Cs+. And then the doped tungsten trioxide material is prepared into the dispersion solution for adding to the preparation of heat insulation coating. Finally, the smart coating is applied to the office building with glass curtain wall to play the role of high infrared shielding and good transmittance in the visible light region. Such coating solves the contradiction of "high transparency and high heat insulation" of the glass curtain walls of the office building. So, tungsten trioxide has extremely high application value.

Tungsten trioxide, mainly tungsten trioxide nanopowder, is often applied for producing dining room heat insulating glass coating. That is because the tungsten trioxide nano particles has excellent shielding effect on near-infrared rays that are not visible to the naked eye. In particular, the infrared shielding rate in the 1000nm band is greater than 90% and the visible light transmittance is greater than 70%.

Tungsten trioxide exhibition hall heat insulating glass coating is a new type of energy saving material with the characteristics of environmental protection, high visible light transmittance and high infrared blocking performance. In addition, this type of smart coating has a far better infrared blocking ability in the near-infrared region with a wavelength of less than 1000 nm, which is far superior to heat shielding coating materials prepared using nano ATO, ITO, and the like.
