Tungsten trioxide, or WO3, is usually doped with alkali metals for producing a promising candidate for applications to near-infrared shielding such as office building thermal insulating glass coating. Wherein these doped tungsten trioxide products are known as tungsten bronze nanoparticles (MxWO3, M = Na, Tl, Rb, and Cs).

Tungsten trioxide is often doped with a group VIII B metal element, and then it is prepared into dispersion for producing study thermal insulating glass coating - a well-known heat shielding material. For the raw material tungsten trioxide powder, the experts dispersed it using ultrasonic separation. And they conducted the structural characterization of the tungsten trioxide powder using X-ray diffraction (Philips by a KCu source with a wavelength of 1.54056 Aº).

Tungsten trioxide for the production of kitchen thermal insulating glass coating can be prepared using sodium tungstate dehydrates (Na2WO4·2H2O, 99.99%,) powder as the starting material, and hydrochloric acid (HCl, 37%) as well as nitric acid (HNO3, 68%) as the chemical materials for ion exchange reaction. Oxalic acid dihydrate powder (H2C2O4·2H2 O, 99.99%) and polyethylene glycol with a chain length of 200 (PEG 200, 99.99%) were used as the complexing agent and polymeric source, respectively. Deionized water was used for solution preparation and washing steps. All the chemicals and solvents were used without further purifications.

Tungsten trioxide for the preparation of balcony thermal insulating glass coating is tungsten trioxide nanopowder, which is regarded as one of the most interesting material in the fields of material science.

Tungsten trioxide for preparing bedroom thermal insulating glass coating is tungsten trioxide nanopowder, more specifically, metal oxide nanopowder, which can be produced by using a chemical method - the sol-gel technique. And the sol-gel method is known as a very simple and inexpensive approach in which shape and size of powder can successfully be controlled.

Tungsten trioxide for the production of living room thermal insulating glass coating is nanostructured tungsten trioxide. It has been confirmed that nanostructured tungsten trioxide exhibits improved properties in comparison to the conventional coarse-grained structures. This is believed to result from the greatly increased surface area, which provides a large interface between the solid and a gaseous or liquid medium to react.

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.
