摘要: 在对装有B/KNO3/RDX的密闭容器中的燃烧产物进行电镜扫描、能谱分析、物理观察以及化学滴定分析的基础上，发现B/KNO3/RDX燃烧产物中含有较多的固态氮化硼，从而提出了一种含能材料爆燃快速合成氮化硼的方法。通过对爆燃获得氮化硼的反应原理等方面的分析，提出了B2O3/NH4NO3配方可能是通过爆燃获得高纯度、高产量氮化硼的理想配方。

Abstract: By scan electric microscope, energy spectroscope, physical observation and chemical dripping, it was found that the deflageration of B/KNO3/RDX produced relatively abundant BN. According to this, a new method of synthesis of BN by the deflageration of energetic materials was proposed. Analyses on the deflageration synthesis principle of BN show that B2O3/NH4NO3 may be an ideal formula for attaining high pure BN.
