| 摘 要： | 以金属镁粉为触媒，以六角氮化硼为原料，其中加入适量比例的氧化镁，在国产六面顶压机上，在约5.0 GPa压力、1 500～1 800 K温度条件下，合成出了颜色均匀、晶形完整的黄色立方氮化硼单晶体。实验结果表明，在Mg-hBN体系中，氧化镁对合成cBN晶体的颜色及合成温度有很大的影响。

| Abstract: | In this paper, we report a method with which yellow cBN crystals are synthesized successfully. hBN is used as raw material and magnesium powder as catalyzer. MgO is added appropriately at high pressure (≈5.0 GPa) and high temperature (1 500～1 800 K) with cubic anvil high-pressure apparatus. The synthesized crystals are of perfect shape and uniform color. The synthesis temperature of the cBN is reduced due to the existence of MgO. |
