The nature of metastable phases of carbon


THE following forms of carbon are already known: rhombohedral and hexagonal graphite, diamond, lonsdailite, carbines, Ries crater carbon, and metallic carbon. We describe here new metastable phases in the carbon system1,2 which we detected while sintering highly dispersed diamond powders. Similar structures were also observed during explosive transformations of pyrographite3 and in natural diamonds4 that had undergone shock metamorphism. In all cases, the observed structures are close to those of the Ries crater carbon5.
