Abstract
Studying the dependence of the degree (α) and rate (ϑ) of the phase transformation of graphite into diamond on the synthesis time at different temperatures of the developed synthetic diamonds using the technology of high-pressure high-temperature synthesis in a metal melt (HPHT), we determined the critical mass of diamonds, which indicates the entry of the system into the stability region of graphite, where the graphitization of diamonds occurs. The role of implanted metals and hydrogen in the formation of synthetic diamonds and on its properties was also investigated.
