| 摘 要： | 立方氮化硼（cBN）晶体随颜色的加深，晶体的晶形越完整，晶体尺寸也越大。采用Mg+hBN、LiH+hBN、Li3N+hBN+B和B+Li3N 4种体系分别合成出了黑色的立方氮化硼晶体。通过光学显微镜、X射线衍射、拉曼光谱等测试分析手段，从合成条件、晶体形貌、颗粒度及残余应力等方面对不同体系合成出的黑色cBN晶体作了比较。结果表明，不同体系的合成效果有很大差别。在实际应用中应该根据需要采用不同的体系，以达到最优化合成目的。

| Abstract: | As well known,cubic boron nitride display more integrated morphology and larger crystal sizes with the color burn.In this paper,black cBN crystals were synthesized in the systems of Mg+hBN,LiH+hBN,Li3N+hBN+B and B+Li3N,respectively.Optical microscope(OM),X-ray diffraction and Raman spectroscopy were used to make a comparison with different black cBN crystals on the aspect of the synthetic condition,crystal morphology,grain size and residual stress.The results showed that the synthesized cBN with the differe... |
