摘要： 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. This allows the carbon to precipitate and grow as diamond on the seed crystal due to the difference in solubility caused by the temperature gradient. The conditions in the reaction chamber housing are maintained so as to suppress crystal growth in at least one direction perpendicular to the direction of the temperature gradient, at the end of the solvent metal. The suppressed crystal growth provides the rough surface of the single crystal which can be connected to a tool and thus provides good adherence between the crystal and the tool.

摘要： An artificial diamond single crystal, at least a part of a surface of the crystal having a rough surface which diffusibly reflects light which is formed by suppressing crystal growth at that surface, and wherein said diamond single crystal is obtained by:providing a diamond synthesis reaction system comprised of a reaction chamber housing having positioned therein a carbon source and a solvent metal arranged in contact with the said carbon source, said reaction system being arranged in a pressure medium;providing a seed crystal in the reaction chamber;providing temperatures of from about 1300.degree. to 1600.degree. C. and pressure of from about 50 to 60 Kb in the reaction chamber which permit diamond to be maintained thermodynamically stable in the reaction chamber housing;heating the reaction chamber 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 so as to migrate the carbon from the higher temperature portion to the lower temperature portion using the solvent metal as a medium; andallowing the carbon to precipitate and grow as a diamond on the seed crystal due to the difference in solubility caused by the temperature gradient in the reaction chamber housing;the crystal growth being maintained for about 10 to 100 hours until the crystal growth in the reaction chamber housing in at least one direction perpendicular to the direction of the temperature gradient reaches the contact surface of the solvent metal with the pressure medium having an irregular rough surface and thereby the crystal growth is suppressed at the surface of the pressure medium to thereby form an irregular rough surface on the crystal.
