一、前言自从人类首次获得人造金刚石以来,已经过去四分之一世纪。最初的人造金刚石是采用超高压装置并通过触媒对碳素材料的作用而获得的。早期的理论研究及以后的实验确定了碳素相图中的石墨—金刚石平衡线(图1)。目前,占世界工业用金刚石总量三
I. INTRODUCTION It is a quarter century since mankind first gained artificial diamond. The first man-made diamond was obtained by using an ultra-high pressure device and acting on the carbon material by a catalyst. Early theoretical studies and later experiments determined the graphite-diamond equilibrium line in the carbon phase diagram (Figure 1). Currently, accounting for the world’s total industrial diamond III
