Introduction:
Dark blue or bluish-purple crystals. The relative density is 3.52 (25°C), the melting point is 275°C, and the boiling point is 346.7°C. Soluble in carbon disulfide, soluble in ether, ethanol, benzene, carbon tetrachloride. It is easily decomposed by hot water, and is oxidized by oxygen in the air to form tungsten oxychloride or tungsten oxide when heated. Tungsten hexachloride containing tungsten oxychloride is easily decomposed by water vapor and reduced by hydrogen at high temperature to precipitate tungsten powder
Characters:
Catalyst in synthesis of engineer plastics PDCPD
Refine of high purity tungsten and preparation of WC
Precursor of nano particle tungsten
Usage:
It is used for tungsten plating by vapor deposition method to prepare single crystal tungsten wire, conductive layer on glass surface and as olefin polymerization catalyst. For tungsten purification and organic synthesis. Can be used in agriculture, chemical industry, petroleum catalysis, and smart glass industries
