Nano particle size violet tungsten oxide may be used to prepare nano-ceramic color master, which is important for manufacturing heat insulation material. So, the raw material --- violet tungsten oxide powder has attracted more attention.
A lot of researchers are still paying attention to violet tungsten oxide as it can not only be used in heat insulation filed, but for producing tungsten powder. As you may have known, blue tungsten oxide can also be used to prepare tungsten powder. While violet tungsten oxide is a better raw material for producing tungsten oxide with finer grain size. Researchers conduct an experiment to verify this result.
First, tungsten powder is prepared using the above two kinds of tungsten oxides as raw materials respectively. And the performance of WC powder prepared under the same conditions using the prepared tungsten powder was analyzed. It was found that particle size of WC powder prepared from violet tungsten oxide was smaller than that of WC powder prepared from blue tungsten oxide. One of the factors that affecting the particle size of WC powder is the particle size of the original tungsten powder. The particle size of the tungsten powder prepared from raw material violet tungsten oxide is small, and the particle size of the further reduced WC powder is also small. In addition, the particle size of WC powder is also affected by the microstructure of tungsten oxide.
