ABSTRACT:
This invention relates to the synthesis of diamond by subjecting a carbon-containing composition substantially free of carbon-hydrogen covalent bonds to conditions of temperature and pressure such as to cause decomposition of the composition to release carbon atoms or groups of carbon atoms and effect conversion of the released carbon atoms or groups of carbon atoms into diamond. The preferred compositions are halogenated compounds, particularly hexachlorobenzene, hexachloroethane and tetrachloroquinone.
