摘要

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.
