Abstract: A high pressure/temperature device for carrying out the synthesis of superhard materials, such as diamond and cubic boron nitride, the device consisting of two dies having recesses in closing faces, said recesses forming, in combination, a highpressure chamber which accommodates a container charged with a reaction mixture. In each die, the recess is made in the form of a truncated cone conjugated with a sphere or in the form of a hyperboloid of revolution.

Abstract: DIAMOND IS SYNTHESIZED BY SUBJECTING A MIXTURE OF GRAPHITE AND A METAL CATALYST TO A TEMPERATURE OF AT LEAST 1150*C. AND A PRESSURE OF AT LEAST 40 KBARS, THROUGHOUT THE ENTIRE VOLUME OF THE CATALYST THERE BEING DISPERSED GRAPHITE CRYSTALLITES. THE PROCESS ENABLES ONE TO PREPARE A LARGE NUMBER OF SEPARATE, SMALL, WELL DEFINED DIAMOND MONOCRYSTALS IN A RELATIVELY SHORT TIME. THE DIAMOND PRODUCT HAS HIGH ABRASION PROPERTIES.

Abstract: An apparatus for developing high temperature and high pressure has a pair of identical dies having opposing cooperating end faces, each face end having therein a spherical cavity and a conically tapering peripheral portion. When the end faces of the two dies are brought closer together, the two spherical cavities conjointly form therebetween a high pressure chamber in which there is received a container made of a plastic material, and the respective peripheral tapering portions form therebetween a gap. The ratio of the radius of curvature of the cavity in each end face to the diameter of this cavity does not exceed 0.75. The volume of the container and its contents is substantially equal to the total volume of the high pressure chamber and the peripheral gap.
