本文分析了致密相氮化硼的动态高压合成条件,用轴对称爆炸装置对石墨型氮化硼进行了一系列加载试验,对回收样品进行了X光衍射试验和扫描电镜观察,结果表明回收样品中黑色部分含有致密相氮化硼。提高试样初始密度,增加炸药量和加限制钢管,明显地有利于致密相氮化硼的生成。 In this paper, the conditions of dynamic high-pressure synthesis of dense phase boron nitride were analyzed. A series of loading tests were carried out on graphite-type boron nitride with an axisymmetric explosive device. The recovered samples were observed by X-ray diffraction and scanning electron microscopy. The black part contains dense phase boron nitride. Increasing the initial density of the sample, increasing the amount of explosives and adding a limited number of steel tubes is obviously beneficial to the formation of dense phase boron nitride.
