Synthesis of diamonds in the C – Mn - Ni - (H) system and the diamond-shaped mechanism

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.

Investigation of some physico-chemical properties of Elaeagnus L. GUM

“…It is possible to use gum Elaeagnus L. to obtain a ceramic mass with a uniform distribution of components with an optimal consistency in producing composite materials with micro-and nanometals and in the transformation of graphite [9,10]. In addition, using this gum, it is possible to obtain different compositions with various dispersed nanofillers, such as modified kaolin and carbon, which can be used to produce paint and varnish or rubber materials [11,12].…”
