Abstract:The solubility of carbon in water at the pressure of 7.7 GPa and at temperatures
of 1000–2900 K is investigated by means of statistical mechanical theory, and it is
found that the excess saturation concentration of carbon in hot water is very
sensitive to the temperature. The peak of excess saturation concentration is
located at 2450 K, according to calculations using the code CHEQ, where the
driving force for graphite-to-diamond transformation reaches the maximum. The
conclusions are consistent with those fro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
