Physical and Chemical Properties | Tungsten hexachloride is a compound of tungsten and chlorine, chemical formula WCl6, appearance appears dark blue or blue purple fine crystal powder, soluble in carbon disulfide, soluble in ether, ethanol, benzene, carbon tetrachloride, easy to be decomposed by hot water, tungsten oxychloride or tungsten oxide is generated by oxidation by oxygen in the air during heating, and WCl6 containing tungsten oxychloride is easily decomposed by water vapor, and is reduced by hydrogen under high temperature conditions to precipitate tungsten powder. tungsten hexachloride (WCl6) is a new material, which can be used for tungsten purification and organic synthesis, or tungsten plating by vapor deposition, and can also be used in chemical industry, or used in the glass industry, mainly in the production of surface coatings. |
