There is another common method to prepare ultra-fine \/ nano WC powder: plasma method, which uses the plasma as the heat source, and its temperature can reach 4000 ~ 5000 \u2103. Under such high temperature, the powder raw materials will decompose and react to produce the required products. This method generally uses WO3, WC or w as the w source and CH4 as the C source. After the reaction, it mainly produces \u03b2- The research of WC or W2C, Japan’s Kuriyama, etc. shows that when the molar ratio of CH4 to WC is greater than 15, \u03b2- The mass fraction of WC is 90%-95% and the particle size of the powder is about 10nm. TEM observation \u03b2- The grain size of WC is 5-20nm, which has good fractional property.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"

As one of the most important raw materials for the production of cemented carbide, the particle morphology, size, particle size distribution and impurity content of\u00a0wolfram\u00a0carbide (WC) powder will directly affect the quality and application of cemented carbide.
