本文主要探讨合成金刚石的压力条件究竟与什么因素有关。静压法需要超高压才能合成出金刚石来,基本上符合石墨——金刚石转变的相图。而现在国内外已研究成功多种在常压下合成金刚石的方法,这与相图又是矛盾的,那应如何解释呢?首先,我们应该承认,由石墨转变成金刚石有二条途径:一个是“固相转化”;另一个是“溶解——结晶”过程。Ю.Л.Оргов说过:“合成金 This article mainly discusses the synthetic diamond pressure conditions and what factors. Hydrostatic method requires ultra-high pressure to synthesize diamond, basically in line with graphite - diamond phase diagram. Nowadays, many successful methods of synthesizing diamond under atmospheric pressure have been researched both at home and abroad, which is contradictory to the phase diagram. How should we explain it? First of all, we should admit that there are two ways to convert from graphite into diamond: one is “Solid-phase transformation”; the other is the “dissolve-crystallize” process.
