六方氮化硼的制备方法及在合成立方氮化硼中的应用

摘要

The preparation methods of hexagonal boron nitride used commonly in China were introduced hriefly. The impurities, particle morphology and crystallinity were tested by inductively coupled plasma atomic emission spectrometry (ICP) . X-ray diffraction, laser particle size analysis and specific surface area tester. The results indicated that the properties of hBN prepared by different methods had no obvious difference. Application of hexagonal boron nitride in synthesizing cubic boron nitride showed that although hBN from different preparation methods had some influence on the color and yield of CBN, they can be adjusted to meet the requirement of CBN synthesis in China, thus providing basic guarantee for cheap and fine products of CBN.%对中国生产六方氮化硼(hBN)的厂家的制备方法进行了研究,采用感应耦合等离子发射光谱(ICP)、X射线衍射、激光粒度分析及比表面积测定等方法对不同方法制备的hBN粉末进行了检测分析对比.结果发现,其杂质含量、颗粒形貌、结晶度等性能无明显的差异,均属纯度一般的粗制hBN.合成立方氮化硼(CBN)的试验及生产使用表明,虽然不同方法制备的hBN合成CBN的效果和适用性有差别,但均能满足我国CBN单晶合成的需要,为国产合成CBN提供了基础原材料保证.
