Abstract
For modeling process of diamond growth by the method of a temperature gradient used model based on three-dimensional probabilistic cellular automata. The model describes diffusion of carbon in metal-solvent, dependence of solubility of carbon on temperature and kinetic phenomena on a crystal surface. The modeling was carried out for system configurations really used for the perfect diamond crystal growth. As parameters of model the real values were used: coefficient of diffusion of carbon in metal - solvent, dependence of solubility of carbon on temperature, geometry of the growth system, temperature and temperature gradient in the high pressure chamber. The results obtained during modeling have quantitative conformity with real processes for dependence of diamond crystal weight on time and geometrical ratio of the crystal sizes.
