摘　　要：在研究ＮｉＭｎ２５Ｃｏ５－Ｃ体系中，金刚石结晶形太与温度压力关系的基础上，实验探索了控制温度压力“准静态”变化过程中，六八面体晶核逐渐“外延生长”，最终生长成为质量较好、晶种法完整的立方体金刚石的方法和规律。Based upon the pre-study of relation between morphology and tempera- ture in Ni 70 Mn 25 Co 5-carbon system,synthesizing methods and growing rules of biamond have been studied experimentally by controlling the change of priessure and tenpoerature in' puasi-static' way,in order that the regarded seeds of spontaneous crystals would grow epitaxially into perfect cubic morphology. The work is useful both theoretically and practically for the synthesizing of large form diamond crystals as heat-sink ma-terial by the reconstitution method.
