Abstract

The morphology and anatomy of diamond crystals with tetragonal depressions on their surface have been studied. Based on the study of the interrelation between tetragonal depressions and the internal structure of diamond crystals, it is concluded that tetragonal depressions are related to the relics of surfaces of polycentric regeneration growth along the 〈100〉 direction. For all investigated crystals of cubic habit, including dissolved ones, surfaces of {111} faces appear in the form of combination hatching in the last growth stage. It is shown that tetragonal depressions have a growth nature in most cases.

摘要

研究了在其表面具有四边形凹陷的金刚石晶体的形态和解剖结构。基于对四方凹陷与金刚石晶体内部结构的相互关系的研究，可以得出结论，四方凹陷与沿<100>方向的多中心再生生长表面的遗迹有关。对于所有立方习性晶体，包括溶解的晶体，{111}面的表面在最后的生长阶段以组合阴影线的形式出现。结果表明，在大多数情况下，四角形凹陷具有生长特性。
