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…

Nanometer tungsten carbide powder is a kind of tungsten carbide powder with a particle size <100nm, which has the properties of the abnormal tungsten carbide powder. It can make the tungsten carbide with more excellent properties. Particle When the particle size of the tungsten carbide powder varies greatly, the characteristic of the powder is obviously different. Especially when the particle size reaches the nanometer level, it often shows the abnormal performance of the conventional tungsten carbide powder. Applications Nanometer tungsten…

Ultrafine tungsten carbide powder is tungsten carbide powder with particle size ≤0.5μm. It is the basic raw material for the production of ultrafine-grained tungsten carbide. It should be sealed in vacuum and cannot be stored for more than 8 months. Particle The particle size of the ultrafine tungsten carbide powder can be measured by using the microscope (SEM, TEM), the laser particle size method, the X-ray line width method and the specific surface area method. The combination of several measurement…
