    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 different system exhibited obvious difference. In order to optimize the cBN synthesis, the appropriate system should be chosen according to diverse demands in practical applications.
