| 摘 要： | Cubic boron nitride is synthesized by the reaction of Li3N and B203 under high pressure and high temperature （4.0-5.0 GPa, 1350-1500℃）. The minimum pressure of cBN formation is 4.0 GPa. The present condition of cBN formation is clearly lower than the eutectic temperature of Li3BN2 and BN in the Li3N-hBN system （5.5 GPa, 1610℃）. The content of cBN in the sample increases, while the content of hBN decreases with the temperature and pressure. The maximum conversion rate （5.0 GPa, 1500℃） is about 34%, which is higher than that in the hBN-Li3N system. The cBN crystals are octahedral or tetrahedral in shape and approximately 20 μm in diameter.
