Nano WO3 powder tungsten oxide partly used in the production of chemical products, such as paint and coating, petroleum catalyst, etc.;But tungsten oxide is a kind of intermediate products, a large number of tungsten oxide is used for metal tungsten powder and tungsten carbide powder production,also include many tungsten alloy products, such as tungsten copper, tungsten nickel, tungsten nickel iron,tungsten silver, tungsten rhenium and tungsten thorium, etc.at the present, the most widely used in the industrial field is cemented carbide products of tungsten base material.
Nano WO3 powder tungsten oxide with gas sensitivity for detecting NO2, NH3 ammonia and other toxic gas. nanometer sensor greatly improved for the low concentration of toxic gas detection.
Tungsten trioxide is used for many purposes in everyday life. It is often used for industrial X-ray phosphor screen and fireproof fabric manufacturing tungstate.Due to its abundant yellow elements, tungsten oxide is used as a pigment in ceramics and paint.
