摘要
β－Ｃ３Ｎ４是由Ｌｉｕ和Ｃｏｈｅｎ等［１～３］从第一性原理出发计算而预言的一种新型超硬材料，据Ｌｉｕ等提出的经验公式计算认为，β－Ｃ３Ｎ４的硬度为４２７ＧＰａ，具有接近金刚石的体模量（理论值为４３５ＧＰａ，实验值为４４３ＧＰａ）．Ｌｉｕ采用可变晶格模...
Cubic C 3N 4 has been produced by pulsed laser inducing the reaction on ammonia solution graphite interface at the first time. Transmission electron microscopy(TEM) and high resolution electron microscopy(HREM) are used to characterize the structure of the cubic C 3N 4. The TEM image of cubic C 3N 4 has been provided, and the graphite lattice, the theoretical cubic C 3N 4 lattice and the experimental lattice of the interplanar spacings have been compared with one another.
