In the high pressure method of growing diamonds with a metallic flux, two phases of carbon, diamond and graphite, or a stable and a metastable phases, can exist and take part in the reaction, simultaneously. This gives a variety to the nature of the driving force for the crystallization of diamond, which can, in turn, be utilized to control the growing process according to the purpose. Behavior of the nucleation process is explained by a reaction model in which the nucleation of diamond and recrystallization of graphite competes. The model can deduce a pressure-temperature cycle for sinthesizing well-crystallized particles suitable to the metal-bond type abrasive use. The model also deduces a new method of growing single crystals using seeds, which is different from the temperature-gradient method.
