Nano violet tungsten oxide powder may be applied for preparing nano-ceramic color master. And the obtained color master has the advantages of high heat insulation and high transparency so that it can be applied for the production of heat insulating film.
Violet tungsten oxide can also be used as a raw material for preparing submicron tungsten powder. Submicron W powder may be prepared by cyclic reduction oxidation method using a relatively simple phase composition of violet tungsten oxide. Compared with the current methods for preparing submicron W powder at home and abroad, the method has the advantages of simple and easy process route, easy control of process parameters and simple equipment.
Why use violet tungsten oxide as a raw material for making submicron or micron W and WC powders?
The grain size of the cemented carbide mainly depends on the size of the WC particles, while the production of submicron or micron WC is very difficult, and the size of the WC particles depends on the size of the tungsten powder particles. It can be seen that the fineness and uniformity of tungsten powder are the key to the preparation of submicron or micron cemented carbide. And it has been reported that submicron or micron W and WC powders can be prepared with a relatively single phase of tungsten oxide such as violet tungsten oxide.
