摘　　要：为了进一步提高我国硬质合金产品的质量，满足科技发展的需要，生产出优质的超细钴粉，本文对四种硬质合金用钴粉的生产工艺的原理及相应产品的性能进行了阐述和比较。相比之下，用热离解法和多元醇还原法生产的产品具有纯度高、粒度细、分布均匀，呈球形等优点，符合目前硬质合金生产的要求。因此。Principles of four processes for producing cobalt powders for hard alloys and properties of the corresponding products are compared.Products produced by pyrolysis and polyatomic alcohol reduction processes have advantages of high purity,fine particle size,good distribution,and spherical powder,that is content with requirements of hard alloy production at present.So the two processes are regarded as the best one for producing cobalt powders for hard alloys.
