摘要: 在石墨─金刚石单组分的两相平衡图理论基础上,从热力学理论观点出发,研究了形成金刚石晶体粒度和晶质的区域分布特征。重点论述粗粒高强金刚石晶体生长区域及热力学条件。以此为理论指导,进行生产试验,获得较好效果。Abstract: In this paper, starting from theory of thermodynamics, we have studied the dispersion characteristic of crystalline-grain and crystalline-quality of diamonds, on the basis of equilibrium diagram theory of graphite-diamond (G-D) phases. The key to the discussion is placed on the growth districts of thick-grain-size diamond and their thermodynamic conditions. Guided by the above-mention theory, we got good results in our productive test.
