Analyzing the Submicron Tungsten Oxide‘s Morphology Producing By Violet Tungsten Oxide (1)

Violet tungsten oxide (VTO) has a special structure and properties, is one of the most suitable materials for producing fine tungsten powder. Using violet tungsten as raw material by hydrogen reduction to obtain tungsten powder, tungsten powder and carbon mixture obtained submicron tungsten carbide powder, and then mixed with carbide powder to form submicron tungsten powder which has great significance for producing outstanding performance superfine alloy. Through the study of tungsten powder and tungsten carbide powder properties so that they can be more widely used in the different fields.

Through data analysis, violet tungsten oxide has special structure which is different form other tungsten oxide. Violet tungsten oxide is combined with rod-like and needle-like crystal, there are non-uniform of thickness, but it has big length-diameter ratio. So the kind of this structure has a lower bulk density which is good for hydrogen reduction reaction. So that the tungsten powder and tungsten carbide powder which produce by violet tungsten oxide can obtain submicron level particle size.
