Kinetics of the graphite?diamond transformation in aqueous fluid determined by in-situ X-ray diffractions at high pressures and temperatures
Source abstract
Abstract
The graphite-diamond transformation was investigated by in situ time-resolved X-ray diffraction experiments using aqueous fluid containing dissolved MgO as the diamond-forming catalyst under conditions of 6.6–8.9 GPa and 1400–1835 °C. The transformed volume fractions of diamond as a function of time under various pressure-temperature conditions were obtained and analyzed using the JMAK rate equation. Variations in the nucleation and growth processes during diamond formation as a function of pressure and temperature were clarified.
