Tungsten dichloride is an inorganic compound with the chemical formula WCl2, which is a black solid that can be prepared by the reaction of tungsten and chlorine. It is an important tungsten compound widely used in the fields of catalysts, ceramics and electronic devices.
Like tungsten hexachloride (WCl6), tungsten dichloride () is also a compound composed of transition metal tungsten and non-metal chlorine, and also has good physical and chemical properties. However, due to the difference in the number of chlorine atoms or the valence of tungsten, the two have slight differences in specific mechanical performance indicators, process parameters and uses.
In terms of chemical composition, tungsten dichloride is a low-valent tungsten chloride composed of one tungsten atom and two chlorine atoms. It is a yellow-brown powder with fine particles and uniform dispersion. Tungsten ions are a polymeric cluster compound with an octahedral structure, the English name is Tungsten Dichloride, the chemical formula is WCl2, the molecular weight is 254.76, and the CAS registration number is 13470-12-7.
In terms of physical and chemical properties, the appearance of tungsten dichloride is yellow-brown powder, soluble in water, hydrochloric acid, ethanol and ether, the density is about 5.44g/cm3, the chemical stability is poor, and it is easily oxidized by air or oxygen to a higher price. State of tungsten chloride, and decomposition reaction will occur under the condition of 500 ℃. In addition, WCl2 can also react with water to generate hydrogen, react with concentrated hydrochloric acid to generate (H3O)2[W6Cl14](H2O)x, and react with hydrogen to generate tungsten powder.
In terms of production, there are four main production methods of tungsten dichloride: one is to reduce tungsten hexachloride with aluminum in the melt of sodium tetrachloroaluminate; It can be prepared by the disproportionation reaction of tungsten chloride; third, it can be prepared by reacting tungsten powder and chlorine gas at high temperature; fourth, it can be prepared by introducing sufficient reducing atmosphere into the tungsten-chlorine-oxygen system.
In terms of use, tungsten dichloride is mainly used to produce other tungsten compounds such as tungsten chloride, tungsten oxide, etc.; it can be used as a raw material in the fields of catalysts and electronic materials; it can be used to prepare high-purity tungsten powder.
