New type equipment for producing super high pressure

Abstract

The invention relates to a new installment for having ultrahigh voltage. It includes 6 hammer heads (4) of 6 sides presser synchronization drive, supercharging unit (1) composed of 8 cubes (6) which cutting one corner each and octahedron synthesis blocks (8) used for holding the synthesis raw material in the internal. Thereinto, putting the turbo-charged unit (1) into the hexahedron high pressure octahedron cavity (9) made of cubes (6) which matches with the unit, and putting the octahedron synthesis block (8) into the octahedron high pressure cavity made of cubes which matches with the block, the deformation strutting whose hardness is smaller than the tangential angle cube is filled among the eight cubes (6) which compose the turbo-charged unit. Composed to the second-level six - octahedron static high pressure installment based on two sides skeleton heads in existence, it is simple structure, high intensity of pressure transfer ratio, few energy consumption of the movement, few service work load and so on.

Description

Technical field [0001] The present invention relates to a pressure device used in material synthesis, and more specifically, a static high pressure device used in superhard material synthesis. technical background [0002] Synthetic diamond, cubic boron nitride (cBN), B 6 The synthesis of superhard materials such as O requires a high-temperature and high-pressure environment. The main equipment used in the synthesis is a large-cavity static high-pressure device. The large-cavity static high-pressure device started from the high-pressure technology developed by Bridgman and others at the beginning of the last century. It mainly includes two-sided and polyhedral pressure-cavity devices. The maximum pressure generated by the two-sided pressure-cavity device (two-sided pressing machine) is about 12GPa, which can satisfy The preparation of superhard materials of general quality is required, but the preparation of higher quality superhard materials requires higher pressure. Polyhedral ...

AI Technical Summary

Problems solved by technology

China ordered a set of two-level hexa-octahedron large-cavity static high-pressure device from the United States, plus the installation cost, the total is about 5 million yuan, which is expensive

In addition, this two-stage hexa-octahedron large-cavity static high-pressure device based on the two-sided pressing machine has a pressure conversion rate due to the design of a slider that converts the double-sided pressing machine into a six-sided pressing machine. Low cost, complex device structure, high energy consumption in operation, heavy maintenance workload, etc.
