据稀有金属网于1995年No1报导，北京有色金属研究总院最近研制成功用等离子体熔炼法制取WC－Co硬质合金粉末。传统的制取方法是要长时间的破碎研磨，工艺冗长复杂。此新工艺可直接得到不同粒度的粉末，可按需要制得不同山含量硬质含金粉末，粉末的氧含量低，一般为0．1～0．15?
According to Rare Metal Net No1 reported in 1995, Beijing Nonferrous Metal Research Institute has recently successfully developed WC-Co cemented carbide powder by plasma melting method. The traditional method is to take a long time crushing grinding, process lengthy and complicated. The new process can be directly obtained with different particle size of the powder can be made according to the needs of different mountain content of hard gold-bearing powder, the oxygen content of the powder is low, usually 0.1 ~ 0.15?
