Nano violet tungsten oxide for producing nano-ceramic color master has a unique fine needle-like structure. Compared with nano blue tungsten oxide and nano yellow tungsten oxide, nano violet tungsten oxide has a special surface and the highest chemical activity, and is more suitable for the production of ultrafine grain size tungsten powder.
The tungsten carbide powder prepared by using nano grain size violet tungsten oxide has a fine particle size and a narrow particle size distribution without structural aggregate block. The prepared nano violet tungsten oxide is of single phase (W18O49). And the ultrafine particle tungsten powder with uniform performance and high quality can be obtained by reduction. In addition, when ultrafine tungsten powder is produced by using nano violet tungsten oxide as raw material, the production cost is greatly reduced. Therefore, in recent years, many manufacturers have begun to try to produce ultrafine tungsten powder by this method. And therefore, more and more scholars have begun to study the production process of nano particle size violet tungsten oxide. Besides, the process parameters affecting the quality of violet tungsten oxide is also studied.
