由文献[1,2]得知,铝是类石墨的BN相变为立方BN变体的触媒。在α-BN原料中添加A1粉末使其转变为立方的β-BN过程能在较低的压力下进行.此外,文献[3]报道了A1在β-BN晶格中是可溶的。本工作提出了查明高温高压下BN相变过程中A1的催化特性和在此条件下β-BN生成机 It is known from literature [1, 2] that aluminum is a graphite-like BN catalyst transformed into a cubic BN variant. The β-BN process of adding A1 powder into the α-BN raw material to convert it into cubic can be carried out under lower pressure.In addition, it is reported in literature [3] that A1 is soluble in the β-BN lattice. This work proposed to identify the phase transition of BN at high temperature and high pressure catalytic properties of A1 and in this condition β-BN generator
