    Abstract: Reaction vessel construction is described for suppressing spontaneous diamond nucleation and simultaneously reducing the flaw content in the main body of diamond grown from diamond seed material by the process broadly disclosed in U.S. Pat. No. 3,297,407 to Wentorf, Jr.In the reaction vessel construction the body of catalyst-solvent metal is formed with at least one small tip projecting from the underside thereof. A single diamond seed is placed in contact with this (or each) tip. The underside of the plug of catalyst-solvent metal is in contact with a nucleation-suppressing disc, or layer, of a material different from the catalyst-solvent and selected from a specific group of materials. In each case the tip of catalyst-solvent metal projects through a hole in the disc or layer to make contact with the diamond seed material.

    Abstract: A process for synthesizing larger size diamonds wherein a raw material carbon substance and a solvent-catalyst metal initially isolated from the carbon substance by a metal having no affinity to carbon are subjected to high pressure-high temperature conditions within a diamond-stable region calculated and defined by a specific combination of the carbon substance and solvent-catalyst metal to temporarily restrict nucleation at the reaction earlier stage to control the number of diamond crystal nucleuses.

    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.
