摘要：
The structure of diamond polycrystals synthesized at different pressures is studied. The direction of crystallite growth in the polycrystals depends on the pressure. On that basis, polycrystalline diamonds may be classified. In the synthesis of polycrystalline diamonds from isotropic graphite, ballas crystals are formed at 6.0-6.5 GPa, carbonado crystals at 11.0-12.0 GPa, and polycrystals of intermediate type at 7.5-9.0 GPa. © 2014 Allerton Press, Inc.
