Violet tungsten oxide is a type of tungsten oxide powder that may be applied for producing an inorganic electrochromic film. And the prepared smart film may be applied to architectural glass to make the room "warm in winter and cool in summer", thereby saving energy and reducing consumption, also reducing the cost of air conditioning for cooling and warming the room.

Violet tungsten oxide may be used to prepare an all-solid-state electrochromic smart window, which is also known as an energy-saving window. Now, such window is widely used in the heat insulation fields of buildings, automobiles, airplanes and spacecraft.

Nano tungsten oxide, as a nano-inorganic electrochromic material, can be a main component of water-based heat insulation glass coating. Tungsten oxide nano powder has unique optical properties, that is, ideal selectivity to the solar spectrum, so it has become the best material for solving the thermal insulation problem in semiconductor materials.

Phosphotungstic acid is an extremely important raw material for producing a thermal insulation film. For example, it can be used to prepare a photochromic material composed of an inorganic/polymer composite material. And the obtained composite photochromic material can be sprayed on the surface of the automobile window, and then sprayed with a varnish to form a window film. Due to its own environmental protection, such smart film is more and more widely applied in automobiles.

Phosphotungstic acid is an important raw material for the preparation of photochromic material such as heat insulation film. For the prepared thermal insulation film, experts said that the transparent film can prevent glare, giving the driver a clear view, ensuring the safety of driving. And it can also shield 90% of the ultraviolet rays, preventing the fading and aging of plastic items and rubber parts. In addition, the super glue of the smart film can also stick the broken glass together to prevent secondary damage to people.

Tungsten oxide, as an electrochromic material, is an important raw material for the preparation of a smart glass. Wherein, the tungsten oxide nano powder can function alone or together with other electrochromic materials to form a composite electrochromic material. According to reports, the research team at the University of Texas at Austin used a nanocomposite material, a combination of amorphous niobium oxide and tungsten oxide nanocrystals to create a new smart glass.

Tungsten oxide, or WO3-X, can be used to prepare an electrochromic thin film, which is an environmentally friendly thermal insulation film. For the raw material tungsten oxide nano powder, it has been found that the surface morphology and crystal structure of the tungsten oxide nano particles largely determine its electrochromic properties. And some experts have also studied the difference in electrochromic properties between crystalline tungsten oxide and amorphous tungsten oxide.

W18O49 nanorod can be used to prepare an electrochromic thin film that can achieve thermal insulating and anti-UV performance. Nowadays, such smart film has been applied more and more to large-area glass such as glass curtain wall and floor-to-ceiling windows to achieve the goal of “warm winter and cool summer”. So, how to prepare tungsten oxide nanorod powder?

Tungsten oxide nanorod can be used to prepare an electrochromic thin film, which can be applied to architectural glass or automotive glass to provide advantages such as heat insulation, energy conservation, UV resistance and electricity reduction.

Blue tungsten oxide can be used to prepare an inorganic electrochromic film, which is then applied to architectural glass to obtain smart glass, for shielding infrared rays that will heat the building without affecting indoor lighting.
