There are many thermal insulation materials, among which tungsten trioxide is the one that has excellent shielding performance on near-infrared and ultraviolet with high transmittance of visible light. And therefore, it is widely applied in the field of thermal insulation film. In recent years, tungsten trioxide, as a synthetic nano…

Nano tungsten trioxide is not only an important n-type semiconductor material, but a kind of transparent thermal insulation nanopowder. And it is also one of the few oxide semiconductors that are easy to realize the quantum size effect. Tungsten trioxide can also absorb electromagnetic waves, and has photocatalysis property and other properties so that it is widely used in fuel cells, chemical sensors, optoelectronic devices and other fields. The application of tungsten trioxide in the field of transparent heat insulation…

Tungsten trioxide powder, as an important transparent thermal insulation nanopowder, has excellent optical properties, and therefore it has a wide application in thermal insulation materials such as building glass and auto glass. The color and optical properties of tungsten trioxide are closely related to its electronic structure. And it is the complex electronic structure of tungsten trioxide that makes the color of tungsten trioxide diverse. The color of the material changes from light yellow to light green when some W6+…

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…

As a transparent thermal insulation material, blue tungsten oxide nanopowder may be used for the preparation of transparent heat-insulating film, and therefore be used in building glass, such as skylight, glass window, glass door, glass curtain wall, and automotive glass, etc. The reason why blue tungsten oxide can be used in these places is that blue tungsten oxide is a kind of photochromic material with high thermal insulation, high near-infrared and ultraviolet shielding characteristics in thermal insulation material. And therefore,…

Why not choose nano blue tungsten oxide as the transparent thermal insulation material you needed? Blue tungsten oxide may make this kind of dingal heat insulation material have the advantages of high heat insulation and high transmittance of visible light, so that it may be used to prepare heat insulation film of building and automobile. And therefore, it makes human body feel more comfortable. And it also saves energy. Most of blue tungsten oxide is produced in a semi-closed electrical…

Blue tungsten oxide powder is a type of transparent thermal insulation material, which may be used to prepare transparent heat insulation film, so that it has excellent ultraviolet and near-infrared shielding characteristics and high visible light transmittance. Therefore, the observation of phase structure of blue tungsten oxide has certain guiding significance for blue tungsten oxide applying to the production of thermal insulation materials. Phase Structure of Blue Tungsten Oxide The composition of blue tungsten oxide is subject to the preparation…

Blue tungsten oxide (BTO) is one of many types of transparent thermal insulation material, which may be used to produce thermal insulation film and heat insulation paper. The BTO can be prepared by using APT as raw material and reducing under certain calcination conditions. APT was used as raw material, and was reduced to blue tungsten oxide under certain calcination conditions. It was found that the morphology of APT affected the morphology of blue tungsten oxide obtained by reduction. APT…

There are many types of transparent thermal insulation nanopowders. Among them, blue tungsten oxide nanopowder has good near-infrared and ultraviolet shielding characteristics and high visible light transmittance. So, the transparent thermal insulation nanopowder can be used for the preparation of transparent heat-insulating film. The particles of the raw material APT powder have relatively regular hexahedral characteristic. And the APT powder is coarse with rough surface and many cracks. It was found by observing the morphology of the blue tungsten oxide…

As a transparent thermal insulation nanopowder, nano blue tungsten oxide has many excellent characteristics, such as high temperature resistance, uniform particle, anti-aging, resistance to acid and alkali, etc., and thus can be used for producing transparent thermal insulation film, which is mainly applied in building glass and auto glass. Some ammonium paratungstate powders produced by different manufacturers and different processes were used as raw material to be reduced to blue tungsten oxide under the same conditions. Tests were conducted to…
