Medium fine grain size tungsten carbide powder has small particle size and high homogeneity. It is the main raw material for the production of tungsten carbide, and can be prepared by direct reduction carbonization.
Preparation
It can be directly reduced and carbonized into tungsten carbide powder by tungsten-containing precursor powder, which is a method suitable for industrial scale production.
The continuous process using direct reduction carbonization can shorten the process flow and increase the efficiency of the generation of medium and fine tungsten carbide powders. At the same time, the obtained medium fine grain size tungsten carbide powder and its alloy powders have better uniformity and smaller particle size.
Application
Due to its high hardness, strength, toughness, abrasion resistance and erosion resistance, medium fine grain size tungsten carbide powder is widely used in the manufacture of precision molds, micro drills, printer needles, and cutting, drilling, and mechanical tools.
