摘　　要：从原料、碳化工艺、粉碎分级等方面探讨了传统流程生产优质超细碳化钨粉的质量控制,并对几种检测超细碳化钨粉粒度的方法进行了比较,结果表明由BET法测定的结果与粉末颗粒的实际尺寸最为接近。Quality control is discussed in respect of material selection, carbonization process and pulverization classification during the production of high-quality ultrafine WC powders by conventional process. Some methods to measure the particle size of ultrafine WC powders are compared. The results show that the BET measured value is the closest to the actual particle size.
