摘要

本文报道了高温高压下纯铁触媒与石墨体系合成磨料级金刚石的过程,并给出了P-T相图.在此基础上,通过调整工艺参数,控制再结晶石墨量与金刚石生长速度,合成出无色透明的金刚石样品,解决了纯铁触媒合成的金刚石透明度较差及包裹体较多的问题.采用穆斯堡尔谱仪和傅里叶红外光谱仪等测试手段,对金刚石样品内部包裹体以及氮元素含量进行了表征,在揭示包裹体形成机理的基础上提出了减少包裹体的方法,同时阐明了纯铁触媒合成的金刚石样品颜色变浅的原因.

Abstract

The synthesis process of grinding compound level diamond by the pure Fe catalyst-graphite system under high temperature and high pressure was reported, and the P-T phase diagram was given. On this basis, the colorless and transparent grinding compound level diamond was synthesized through the adjustment of technical parameters. By controlling the growth speed of recrystallization of graphite and diamond, and the problem of diamond being opaque and presence of inclusions when synthesized by the pure Fe catalyst was solved. According to the analysis of Mmössbauer and Fourier infrared spectroscopy, the inclusions and content of nitrogen element were characterized. Based on clarifying the formation mechanism of inclusions, the solutions to reducing inclusions were achieved. It also demonstrated the reason why the color of diamond synthesized by the pure Fe catalyst turned tinted.
