On the Industrial Production Practice of Super-fine Carbonization Tungsten Powder

With increasing market demand for super fine carbonization tungsten powder,the industrial production of it has become the focus of tungsten industry.This paper introduces the purple oxidation hydrogen reduction,which is optimized out of conventional technology.Super fine tungsten powder with average grain size of 0.1 μm and carbonization tungsten powder with average grain size of 0.1 μm are produced by this technology.
