【Know Tungsten】Nano Tungstic Acid

1. Nano Tungstic Acid
Nano tungstic acid has a large specific surface area and significant surface effect. 

2. Nano Tungstic Acid Specification
Nano tungstic acid has WO3 content over 90%, the grain size is 30~50 nano meter, specific surface area is large, the appearance is yellow powder.

3. Nano Tungstic Acid Application
Nano tungstic acid is a very good catalyst. It can be used as both a main catalyst and an auxiliary catalyst, and has a high selectivity to the reaction. Its main content WO3 has a strong ability to absorb electromagnetic waves and can be used as an excellent solar energy absorption material and recessive material. WO3 is an n-type semiconductor material with excellent gas sensitivity and sensitivity to various gases such as NOx, H2S, NH3, H2, O3, etc., so it can be used to make gas sensors and gas-chromic devices.

In addition, tungstic acid as a cathode material also has a higher theoretical capacity (693mAhg-1). Compared with cobalt, it has low cost and environmental friendliness. Its use in the production of lithium-ion battery anode materials has achieved industrial mass production and is expected to gradually replacing cobalt as the main raw material for lithium-ion batteries which will greatly reduce the cost of electric vehicles.

Tungstic acid is also used as painting material for ceramic due to its shine color and anti-corrosion property.
