摘要

摘要: 通过爆轰合成超细金刚石实验，对装药在不同环境下引爆后得到的固相碳产物进行比较分析，研究不同介质如氮气、水、冰、遇热分解的盐等对爆轰产物中固相碳形成的影响，同时提出用石墨化程度来比较这种影响。结果显示，介质对爆轰产物中固相碳的石墨化和超细金刚石的保护有着重要的作用。几种介质中水的保护效果较好。

Abstract: In this paper, the comparison of the effect of different preservative materials on preserving the condensed carbon obtained from detonation soot shows that the surrounding substance has prominent importance on the formation of condensed carbon in detonation which not only take a preservative effect but also a cooling effect to compress graphitization. For carbon, different circumstance corresponds to different path on carbon phase diagram while detonation product expanding. This provides a clue of improving yield of ultrafine diamond (UFD) obtained from detonation soot. Also in this paper, it proposes the graphitization of graphite crystallite existing in soot and UFD as a criterion to evaluate the preservative effect of different substances.
