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.
