摘要： 本文利用含热分析、热腐蚀实验、扫描电镜和抗压强度实验等方法，研究了人造金刚石在空气中的热稳定性，测定了人造金刚石在空气中的氧化温度，分析了金刚石颗粒在空气中的氧化过程与机理．

关键词: 人造金刚石, 氧化, 热稳定性

Abstract: The thermal stability of synthetic diamond in air was investigated by means of DTA, heat corrosion, SEM and compressive strength test. The oxidation decomposition temperature of the synthetic diamond in air was measured. Oxidation process and oxidation mechanism of the synthetic diamond in air were discussed.

Key words: synthetic diamond, oxidation, thermal stability
