摘要: 本文由实验确定了常压下合成的Mg3B2N4触媒和Mg3N2-BN体系在高温高压下都转变成相同的高压相Mg3B2N4。本文还讨论了Mg3B2N4和Mg3N2触媒的异同。认为用常压合成的Mg3B2N4作为初始触媒对于合成立方氮化硼是有利的。Abstract: This study confirms experimentally that both of the low pressure phase of the Mg3B2N4 and Mg3N2-BN will convert to the same high pressure phase of Mg3B2N4 under high pressures and high temperatures. The similarities and the differences between Mg3B2N4 and Mg3N2 catalysts are discussed. We point out that the low pressure phase of Mg3B2N4 will be favorable to the synthesis of cBN.
