Product Description

Product Description

 

Tungsten Trioxide Powder Nano Grade -100Mesh

Molecular formula: WO₃
Molecular weight: 231.86
Specific gravity: 7.16g/c m3

Appearance:
Light yellow triclinic powder crystals, light yellow heavy powder, which turns dark orange when heated, and restores its color when cold. When the temperature is higher than 740ºC, it will transform into orange tetragonal crystals, which will return to the original state after cooling

Uses:
It can be used as a raw material for making metal tungsten, making cemented carbide, cutting tools, molds, and drawing tungsten wires. It can also be used for powder metallurgy, and it can also be used for X-ray screens and fireproof fabrics, and as a colorant and analysis of ceramics. Reagents, etc., are used as important anticorrosive paint and coating materials in the shipbuilding industry;
Used to make metal tungsten, alloy steel, fireproof fabrics, etc., and used in the ceramic industry;
It can be used as a raw material for making metal tungsten, making cemented carbide, knives, molds, and drawing tungsten wires. It can also be used in powder metallurgy. It can also be used in X-ray screens and fireproof fabrics, as well as colorants and analytical reagents for ceramics. .
Yellow tungsten oxide is used in electroplating and the production of other cobalt products, barometers, and hydrometers;
Blue tungsten oxide is used to produce tungsten powder, doped tungsten powder, tungsten rod, tungsten rod and cemented carbide.
