Blue Tungsten Oxide and Micro-Tungsten Powder

Blue tungsten oxide refers to a dark blue compound typically formed in solution and containing a mixed valence of tungsten and tungsten. Wet tungsten oxide will appear blue when exposed to ultraviolet light. Industrially mentioned blue tungsten oxide refers to the composition of WO_2.72, WO_2.90 and other mixtures.

Micro-tungsten powder refers to particles of Fischer-Tropsch grain size of 0.5μm ~ 1μm tungsten powder, the industrial production of such tungsten powder and technical performance of commercial products remains to be improved.

The quality of the finished production of tungsten powder manufactured through industrial production is related to its purity .The higher the purity, the better the quality of the tungsten powder. The blue tungsten oxide hydrogen reduction process can realize the better scale of industrial production of tungsten powder, and the purity of the finished tungsten powder is high. It is a high-quality raw material powder for producing the fine grains and superfine grain cemented carbides. In the process of hydrogenation of blue tungsten oxide, it is required that the hydrogen dew point range during hydrogen reduction is wide because the excessively dry hydrogen gas is not conducive to the production of fine tungsten powder with uniform particle size and low oxygen content so as to produce high purity tungsten powder production.
