Fine particle tungsten carbide powder has smaller particle size, high specific surface area and good catalytic activity. It can replace precious metal as catalyst, but also can be used as raw material for the production of tungsten carbide.
Particle
The main influencing factors of fine particle tungsten carbide powder are the particle size and the composition of the tungsten powder. Due to the carbonization process is mainly achieved by the reaction of the surface of the tungsten powder particles with the carbon-containing gas and the diffusion of the solid carbon black into the tungsten powder. Carbonization temperature, carbonization time and the carbon content of the material on the impact of tungsten carbide powder size is relatively small.
Application
Fine particle tungsten carbide powder can produce tungsten carbide with high hardness, high wear resistance and high toughness, and its characteristic is obviously higher than that of hard alloy.Fine particle tungsten carbide powder has a high specific surface area and has good catalytic activity, which can replace the traditional catalysts such as precious metal Pt, Pd and Ir.
