A STUDY OF THE PRESSURE-TEMPERATURE CONDITIONS FOR DIAMOND GROWTH

An attempt to unify the growth mechanisms and conditions for diamond f ormation is developed via the growth probability calculated by a barri er model between the two phases. From the distribution law of the equa l growth probability Lines plotted in a pressure-temperature (P-T) dia gram, five regions of different growth methods and mechanisms were rea sonably delineated. Many experimental results can be generalized and e xplained by our theory, and the unity of diamond growth mechanism was discussed over the wide region of the P-T condition.
