石墨——金刚石转变是在超高压条件下,在某些熔融金属溶液中进行的。本文指出,这一结晶体系中的温度差有利于介稳相石墨的结晶,从而解释了金刚石稳定区介稳相石墨结晶的热力学可能性,计算了一个结晶条件下石墨可能结晶的临界温度差。讨论了本工作的局限性和在同素异形体借溶液转变的研究中有待进一步解决的问题。
Graphite-diamond transformation is carried out in some molten metal solutions under very high pressures. It is pointed out in this paper that the temperature difference in this crystal system is conducive to the crystallization of metastable graphite, which explains the thermodynamic possibility of metastable graphite in the stable region of diamond and calculates the critical temperature difference of possible crystallization of graphite in a crystalline condition. The limitations of this work and the problems that need to be further solved in the study of transformation of allotropes by solution are discussed.
