Process Parameters influence Blue Tungsten Oxide Reducing Tungsten Powder Particle Size

In addition the blue tungsten oxide form affects tungsten powder particle size the process parameters also affect the size of tungsten powder. Influence of Process Parameters on the tungsten powder particle size is mainly hydrogen mode, heating systems and hydrogen influence humidity. There has two kinds of hydrogen mode one is cis hydrogen mode and the other is inverse hydrogen, the study found that cis hydrogen mode reduction of tungsten powder particle size is significantly thinner than the inverse hydrogen mode. ATB phase blue tungsten powder at low temperature with cis hydrogen mode can producing tungsten powder particle size thinner, narrow distribution, and the nature the better. In heating system, the researchers found that heating from a low temperature and the heating process more gentle process are good for the producing fine tungsten powder. At the same time hydrogen humidity also impact on the tungsten powder particle size, at the same other process parameters, continuously push the boat and single boat reduction effect is not the same, which is mainly due to different hydrogen humidity. Cis hydrogen mode is good for retrain tungsten powder grow up so producing of fine particles tungsten powder should be used cis hydrogen mode.
