在压力为14.0GPa、温度为3300°K的条件下，由石墨和六方氮化硼的混晶直接相变得到金刚石和立方氮化硼的混晶。该晶体可以用化学式（BN）xC 1 −x（0 < x < 1）描述，具有闪锌矿结构，并且在第一配位层中表现出由C-C对取代B-N对的短程有序。相变具有重构性，并保持了两种结构之间的关系：类石墨结构的001面与类金刚石结构的III面保持平行。
Mixed crystals of diamond and cubic boron nitride were obtained by the direct phase transformation at a pressure of 14.0 GPa and in temperature about 3300°K of mixed crystals of graphite and hexagonal boron nitride. The crystals, which can be described by the formula (BN)xC1−x, 0 < x < 1, possess sphalerite structure and show short range order expressed by substitution of B-N pair by C-C pair in the first coordination sphere. The phase transformation has a reconstructive character and keeps relation between two structures: 001 plane of graphite — like structure remains parallel to III of diamond — like structure.
