Journal ArticleDOI
Synthesis of diamond from graphite-carbonate system under very high temperature and pressure
TL;DR: In this article, high pressure experiments were carried out in the mixture of graphite and the carbonates of Li, Na, Mg, Ca and Sr. The results showed that diamond can be synthesized from graphite in the presence of these carbonates at high pressure and temperature of 7.7 GPa and 2150°C.
Journal ArticleDOI
Segregative Crystallization of Several Diamond-like Phases from the Graphitic BC2N without an Additive at 7.7 GPa
Journal ArticleDOI
Simultaneous crystallization of diamond and cubic boron nitride from the graphite relative boron carbide nitride (BC2N) under high pressure/high temperature conditions
TL;DR: In this paper, a powder X-ray diffraction pattern revealed two kinds of cubic phase, in approximately equal amounts, which were identified as diamond and cBN on the basis of their lattice parameters.
Journal ArticleDOI
Phosphorus: An Elemental Catalyst for Diamond Synthesis and Growth
TL;DR: In the present study, diamond was synthesized from graphite in the presence of elemental phosphorus at high pressure and temperature (7.7 gigapascals and 1800C) and single-crystal diamond was grown on a diamond seed crystal.
