What are the characteristics of tungsten oxide?
What is Tungsten Oxide powder?
Tungsten trioxide is an oxygen vacancy metal oxide with the chemical formula WO3-x. According to the different oxygen content, it can be divided into yellow tungsten oxide (WO3), blue tungsten oxide (WO2.90), purple tungsten oxide (WO2.72), white tungsten oxide (WO2.72) and brown tungsten oxide (WO2). Because of their different molecular structures, their physical and chemical properties are also different.

Because of their different molecular structures, their physical and chemical properties are also different.
WO3 is a relatively stable powder in tungsten oxide, with a specific gravity of 7.16g/cm3, a melting point of 1473℃, a boiling point of 1750℃, and 850℃. It is insoluble in water and inorganic acids except for hydrofluoric acid but soluble in alkaline solutions, with a special color, but usually yellow. The crystal size is about 1.5um, which is yellow; The crystal size is about 15um, which is green. The structure depends on temperature, and monoclinic structure is the most common.
WO2.90 is the most common blue tungsten oxide, in which the tungsten content is between 80.00% and 80.80%, the density is between 2.4 and 2.8g/cm3, and the particle size is between 12 and 12~19um. The color is influenced by illumination, which is light blue under illumination and dark blue under darkness.
WO2.72 is quite different from other tungsten oxides in structure, and its inherent crystal form is needle-like and rod-like, so it has the characteristics of rich cracks, large gaps, and low bulk density.
WO2 is an unstable compound, which is easily oxidized to WO3 under oxidation conditions and easily reduced to metal W under reduction conditions. It is 10.9 ~ 1.1g/cm, its melting point is 1500~1600℃, its boiling point is about 1730℃, and it is insoluble in water, alkali solution, hydrochloric acid, and dilute sulfuric acid.
Characteristic of Tungsten Oxide powder
Generally speaking, tungsten oxide is a product produced by calcining and reducing ammonia paratungstate as raw material. According to the different oxygen content, calcination time, calcination temperature, reduction time, reduction gas concentration, and other factors are different.
Tungsten oxide can be used as an additive for smart glass, thermal insulation coatings, and other chemicals because of its good electrochromic, photochromic, and near-infrared absorption characteristics and ultraviolet-blocking effect. Because of its obvious surface effect, excellent gas-sensing characteristics, and semiconductor effect, it has become the first choice for gas-sensing and humidity-sensing materials. Because of its high theoretical specific capacity and good electrochemical performance, it has become the preferred anode material for lithium-ion batteries. Generally speaking, tungsten oxide has a wide range of uses; besides the above-mentioned uses, it can also be used as a catalyst for the petrochemical industry, a colorant for paint, an additive for fireproof fabrics, a main raw material for tungsten products and cemented carbide, etc.
Price of Tungsten Oxide powder
Tungsten Oxide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Tungsten Oxide powder. A large amount of large amount will be lower. The price of Tungsten Oxide powder can be found on our company's official website.
