| description | The invention discloses a hexagonal diamond and a preparation method thereof, and relates to the technical field of diamond preparation. The preparation method of the hexagonal diamond comprises the following steps that (1) quasi-uniaxial pressure is applied, specifically, pressure is applied to a graphite material in the three-dimensional x-y-z direction, the pressure in the x direction is 12-40 GPa, the pressure in the y direction is 12-40 GPa, the pressure in the z direction is 15-50 GPa, and the pressure in the z direction is larger than the pressure in the x direction and the pressure in the y direction; and (2) heating: heating the graphite material to 300-2000K, and keeping the temperature for 1 minute to 5 hours, so as to obtain the hexagonal diamond. The hexagonal diamond prepared by the method has higher purity and a better crystal structure.
本发明公开了一种六方金刚石及其制备方法，涉及金刚石制备的技术领域。一种六方金刚石的制备方法，包括以下步骤：(1)施加准单轴压力：在三个维度x-y-z的方向上对石墨材料施加压力，其中，x方向的压力为12-40GPa，y方向的压力为12-40GPa，z方向的压力为15-50GPa，且z方向的压力大于x方向和y方向的压力； |
