摘要

摘要: 采用高温高压方法，以六角氮化硼（hBN）为原料、选用氮化锂（Li3N）、氢化锂+氮化锂（LiH+Li3N）、氢化锂（LiH）、氢化锂+氨基锂（LiH+LiNH2）、氮化锂+氨基锂（Li3N+LiNH2）为触媒，在合适的温度、压力及生长工艺条件下，分别得到了厚板状、类球形、八面体或六八面体、扁锥状和片状六边形形貌立方氮化硼（cBN）晶体。总结了不同锂基触媒/添加剂对合成的cBN晶体形貌变化的影响。

Abstract: By high pressure and high temperature (HPHT) method, we used hexagonal boron nitride (hBN) as raw materials, Li3N, Li3N+LiH, LiH, LiH+LiNH2, Li3N+LiNH2 as catalyst, and successfully prepared thick plate, spherical, octahedron or hex-octahedron, flat cone and flaky hexagon morphology cubic boron nitride (cBN) crystals with relevant growth conditions. It was summarized that various Li-based catalysts/additives had distinct effects on the cBN crystal morphologies synthesized.
