Nano tungsten oxide, an important industrial raw material, is a compound of tungsten with grain size less than 100nm. Nano WO3 can be used to prepare nano tungsten powder and nano tungsten carbide powder. Early, common nanometer tungsten oxide producing method is solid phase reaction method.
Solid phase reaction method, a traditional method, refers to mix metal salt or metal oxide with a certain ratio, after grinding, calcinate it by solid phase reaction, and then micron powder is obtained. 
Applications:
1. A well performed catalyst, with a large specific surface area, the surface reaction is efficient.
2. A multi-dingal semiconductor dingal material with many properties such as electrical/optical/gasochromic properties (sensitive to multiple gases such as hydrogen sulfide, ammonia, etc.) and superconductivity.
3. In the military, can be used as an important invisible material; In the solar energy, can be used as an excellent absorbent material. That is because Nano Tungsten oxide has strong absorption capacity for magnetic wave.
