【Abstract】 The importance of T-P path in the growth of diamond crystal has been described. Thechanges of temperature in the center of high pressure cell with time were measured withboth direct and indirect heating methods by means of cubic high pressure apparatus. Basedon the experimental results, the time effect on temperature in the center of ultrahigh-pressure cell during rise of temperature and the formula there of have been proposed. Akinetic equation has also been derived. Finally, the principle of determining the optimum curve of rising temperature for thesynthesis of diamond with quasihydrostatic high pressure apparatus is discussed.更多还原
