Preparing Ultrafine Tungsten Carbide By Purple Raw Materials

Superfine carbide with high hardness and wear resistance, high strength and toughness and good high temperature properties, has been widespread attention, has become an important direction of development in the world today carbide. Superfine carbide cutting in difficult areas has been widely used, but also meet the needs of the rapid development of electronic technology for integrated circuit board drilling micro drill. Currently there are dozens of brands of ultra-fine carbide, since the study of ultrafine Carbide performance optimization has been ongoing.

Superfine carbide with high hardness, high wear resistance, excellent performance, ensuring ultra-fine carbide grain size small and uniform is a key factor in size small, evenly distributed ultrafine WC powder as raw material. During the preparation of ultrafine WC powder, commonly used materials for blue tungsten oxide, tungsten less to purple as the raw material preparation process coverage. Using the same process, respectively, blue and purple tungsten raw materials for the preparation of ultrafine tungsten WC powder, and uses the same process for the preparation of ultrafine tungsten carbide, for comparing the performance of both products, found in purple tungsten as raw material out Ultrafine carbide grain size, high strength and hardness has good overall performance.
