Part of tungsten oxide is used in the production of chemical products such as paints and coatings, petroleum industry catalysts, etc. However, oxide is an intermediate product and a large amount of tungsten oxide is used for metal tungsten powder and tungsten carbide powder for the production of tungsten metal products And the large number of applications and production of tungsten alloy products, into the tungsten copper, tungsten nickel, tungsten nickel iron, tungsten silver, tungsten rhenium, tungsten thorium, etc., while the most widely used in contemporary industrial areas is based on tungsten as a substrate Production of various grades and uses of cemented carbide products.
Tungsten oxide with gas sensitivity for the detection of nitrogen dioxide, ammonia and other toxic gas detection. Currently, tungsten oxide film gas sensors and tungsten oxide nanoparticle sensors have been prepared. The discovery of nano-sensors has greatly enhanced the detection of low-concentration toxic gases.
