Abstract
The utility model discloses a novel axial supercharging diamond synthetic block which comprises a graphite column, electric conducting steel rings and pyrophyllite blocks, wherein the electric conducting steel rings are arranged at both ends of the graphite column, and the pyrophyllite blocks are arranged at the periphery of the graphite column and the electric conducting steel rings; the interiors of the electric conducting steel rings are filled with composite fillers; a heating element is arranged at the periphery of the graphite column; the graphite column is formed by two graphite column half-blocks, the end surfaces of which are butted; graphite sheets are arranged between the butted end surfaces of the graphite column half-blocks; and the pyrophyllite blocks are arranged between the graphite sheets and the end surfaces of the graphite column half-blocks. The novel axial supercharging diamond synthetic block adopts an axial supercharging assembling manner and has a simple structure; as pyrophyllite has good pressure transmitting performance, a pyrophyllite rod axially arranged at the middle part of the graphite column can play role in transmitting pressure from the middle to two ends under an ultra-high temperature and high pressure condition; pyrophyllite sheets can be used for effectively making up the insufficient pressure of the middle part of the synthetic block, preventing the interior of the graphite column from being empty and are safe and reliable; the graphite sheets lead the temperature of the graphite column half-blocks to be uniform, so that the yield and quality of products can be greatly increased, and the proportion of fine crystals of a diamond product can be increased from 30% to about 40%.
Description
Technical field
The utility model belongs to the superhard material synthesis technical field, particularly a kind of novel axial supercharging diamond synthesis block.
Background technology
In the synthetic field of superhard material, the synthetic piece under the superhigh-temperature and-pressure condition is the insulation component of the graphite post made by graphite and catalyst mixed powder, graphite post periphery and heating element heater, the conducting steel ring at graphite post two ends, the blocks that the pressure transmission sealing medium assembles according to certain way.Concrete assembling mode is: assembling successively from outside to inside, peripheral pyrophyllite and the dolomite complex media of adopting is as the pressure transmission encapsulant, the conducting steel ring heating of switching on is adopted at two ends, conducting steel ring closely contacts with the heating element heater of inboard, make heating element heater heating itself by conducting steel ring during energising, insulation component through the inboard closely contact of heating element heater reaches heat and the inboard graphite post that closely contacts of insulation component then, makes graphite and catalyst be converted into diamond under the superhigh-temperature and-pressure condition.
From the assembling mode of synthetic piece, under the superhigh-temperature and-pressure condition, the regularity of distribution of pressure is in the graphite post: in axial direction, the pressure at two ends height, intermediate pressure is low; Radially, peripheral pressure height, internal pressure is low, and the pressure in graphite post centre is minimum.Therefore, synthetic piece is more little, and its each site pressure gradient is more little, yields poorly but single is synthetic, and production efficiency is low, deficiency in economic performance; Synthetic piece is big more, and its each site pressure gradient is just big more, because the synthetic output of barometric gradient ambassador single does not obviously improve, quality but obviously descends.
In recent years along with the continuous progress of technical merit, the synthetic cavity of superhard material industry cubic hinge press synthesis device diamond synthesis enlarges rapidly, synthetic piece is big, cause its each site pressure gradient big, the pressure distribution situation that the graphite post presents from outside to inside is for more and more littler, the pressure distribution inequality, thus cause in the graphite post empty.The interior empty situation of synthetic piece makes diamond particles air entrapment, the impurity of generation many easily, and defective is many, and particle is little, has a strong impact on adamantine product yield and quality.
If raising synthesis pressure simply, then can cause the peripheral pressure height of graphite post, make the diamond of peripheral growth become glomerocryst, and can directly have influence on service life of cubic hinge press synthesis device and auxiliary accessories thereof, severe patient directly causes the equipment blast of rupturing under HTHP, not only improve production cost greatly, but also had certain potential safety hazard.Empty problem in the graphite rod, thus the service life of cubic hinge press synthesis device and each auxiliary accessories and product, the quality of diamond product improved.
The utility model content
The purpose of this utility model provide a kind of simple in structure, stressed evenly, can effectively prevent novel axial supercharging diamond synthesis block empty, safe and reliable in the graphite post.
For achieving the above object, the technical solution of the utility model is: a kind of novel axial supercharging diamond synthesis block, comprise the conducting steel ring at graphite post, graphite post two ends and the pyrophyllite in lumps of graphite post and conducting steel ring periphery, be filled with compounded mix in the conducting steel ring, graphite post periphery is provided with heating element heater, described graphite post is made of two graphite post half blocks of end face butt joint, is provided with graphite flake between the graphite post half block butt joint end face, is provided with the pyrophyllite sheet between graphite flake and the graphite post half block end face.
