Subultrafine tungsten carbide powder refers to tungsten carbide powder with a particle size of 0.1~0.3μm. It is a basic raw material for the production of ultra-fine-grained tungsten carbide and can be prepared by phase transfer synthesis.
Application
Subultrafine tungsten carbide powder is the basic raw material for the production of ultra-fine grain tungsten carbide. With the addition of suitable binders and grain growth inhibitors, it can produce high hardness, high wear resistance and high toughness. The quality of the alloy material is significantly higher than that of the conventional tungsten carbide, and it is used more and more widely.
Preparation
Phase transfer synthesis is a commonly used method for the preparation of subultrafine tungsten carbide. Compared with other preparation methods, this method has the characteristics of low equipment investment, low cost, easy to control and reproducibility, and easy to realize industrial production.
