Assembly for super-hard material synthesis

Abstract

The invention provides an assembly for super-hard material synthesis. The assembly comprises a pyrophyllite block, heating subassemblies and pressure maintaining subassemblies, wherein the heating subassemblies and the pressure maintaining subassemblies are arranged in the pyrophyllite block. The pyrophyllite block is a cuboid block with three sets of opposite faces, wherein at least two sets of the three sets of the opposite faces are provided with through holes used for combining inner cores, the inside of each through hole is provided with one heating subassembly and one pressure maintaining subassembly, and the heating subassemblies in any two through holes are not in contact with each other. The inner cores are placed in the through holes, and heating and pressure maintaining are carried out on the inner cores through the heating subassemblies and the pressure maintaining subassemblies, so that synthesis is finished. Due to the fact that at least two through holes are formed in the assembly, compared with an assembly with only one through hole, the assembly can produce more products once and improve inner core production capacity; besides, at least two through holes are formed in the assembly, any two heating subassemblies are not in contact with each other, temperatures of the insides of the through holes keep the same, in the production process, two inner cores can be arranged in each through hole, uniformity of temperature field distribution of the inner cores in each through hole can be guaranteed, and stability of product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of superhard material production, in particular to a component for superhard material synthesis. Background technique [0002] At present, superhard materials produced at home and abroad include diamond, cubic boron nitride, and polycrystalline diamond composite sheets. In the process of producing these materials, although there are various combinations, the components used for their synthesis include pyrophyllite pressure transmission blocks, steel rings, high-temperature resistant metal conductive sheets, heating tubes, pressure-holding tubes and inner cores, etc. . Among them, pyrophyllite plays a vital role in the production of superhard materials: pressure holding, pressure transmission, sealing, heat-resistant heat preservation, insulation, etc. [0003] like figure 1 As shown, the traditional pyrophyllite block 01 has a cube structure, and through holes are opened on its upper and lower sides, that...

Problems solved by technology

If you want to increase the number of inner cores, it is difficult to ensure that the temperature of the middle inner core is the same as that of the outer inner core, resulting in unstable performance of the product
