摘要
本文分析研究了两种冲击法合成的超细金刚石粉的显微结构特征，包括粒度分布、点阵常数、晶粒度和形貌，并根据X射线衍射强度计算了纳米金刚石粉的德拜特征温度。差热分析（DTA）表明两种超细金刚石粉在空气中的起始氧化温度相同，但由于粉末粒径的差异，金刚石及杂质石墨的放热峰温度分别相差35℃和50℃。
A study was made on the microstructure of ultrafine diamond powders synthesized by two different explosive methods including particle size distribution, lattice parameter, brain size and morphology. The Debye characcteristic temperature was also calculated fain X-ray diffraction intensities. DTA indicates that two kinds of diamond powders have the same initial oxidation temperature, but their exotermic peaks of diamond and graphite impurity have a little difference of 35℃ and 50℃ respectively.
