热压温度确定原则及低温活化烧结

THE PRINCIPLE OF DETERMINING HEAT PRESSING TEMPERATURE AND ACT IVAIED SINTERING AT LOW TEMPERATURE

评述了金刚石制品热压烧结温度判定的理论依据，介绍了添加微量元素降低ＹＧ合金烧结温度的机理；同时提及粉末细化、粉末预合金化。

The theoretical basis of checking and determining the sintering tem perature of diamond products is reviewed, and the activated sintering technologies,such as powder fining,powder allow in a dvance and REE alloying,are also discussed.
