Liquid phase synthesis of diamond in hydrogen atmosphere
Graphite can be converted to diamond under high pressure by the catalytic influence of certain molten metal. The transition is reversed at low pressure. However, if hydrogen atoms are available in the atmosphere, graphite may be gasified to form methane, and the latter deposited on the molten metal as diamond.
