Molecular formula: WO3 Molecular weight: 231.86 Specific gravity: 7.16g/cm3 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. | |||||||||||||
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. | |||||||||||||
