Abstract: Based on the non-equilibrium thermodynamic coupling model, the ternary C-H-O stationary non-equilibrium states phase diagrams are calculated under different temperature and pressure in this paper. The calculated results of the isothermal sections show that the whole diamond growth region will gradually rotate anti-clockwise around its core with the substrate temperature increasing while its shape changes greatly.

Key words: phase diagram, non-equilibrium thermodynamics, diamond
