  • Patent number: 4632817
    Abstract: A diamond synthesizing method carried out under diamond-stable superhigh pressure and temperature by employing a synthesizing vessel (10) having a plurality of synthesizing chambers (10a, 10b) divided by a partition layer (16) in the vertical direction. Solvent metals (13a, 13b) respectively placed in the upwardly arranged synthesizing chamber (10a) and the downwardly arranged synthesizing chamber (10b) are prepared so that the solvent metals are different in eutectic temperature with carbon from each other. In the respective synthesizing chambers (10a, 10b), carbon sources (12a, 12b) are placed in contact with highest-temperature portions of the respective solvent metals (13a, 13b) and seed crystals (11a, 11b) are placed in contact with lowest-temperature portions thereof. The synthesizing vessel (10) is provided with a temperature gradient in such directivity that the upper part thereof is at a higher temperature and the lower part is at a lower temperature.

  • Patent number: 4544540
    Abstract: An artificial diamond single crystal, a process for producing it, and tools for utilizing it are disclosed. The artificial diamond crystal has at least one surface which has a rough surface formed by suppressed crystal growth at that surface. The single crystal is produced by providing a diamond synthesis reaction system comprised of a reaction chamber, a carbon source and a solvent metal arranged in contact with the carbon source. A seed crystal is provided in the reaction chamber under elevated pressures and temperatures which permit diamond to be maintained thermodynamically stable. The reaction system is heated to provide a temperature gradient in such a way that a portion of the solvent metal in contact with the carbon source is higher in temperature than a portion of the solvent metal in contact with the seed crystal. This temperature gradient causes a migration of the carbon from the higher temperature portion to the lower temperature portion using the solvent metal as a medium.
