A homogenous internal supercharging assembling way of a pressure field is adopted, so the structure is simple; the pyrophyllite bar and the pyrophyllite sheet have an effect for transferring the pressure to different directions from the center under the condition of ultra high temperature and high pressure, so the shortage internal pressure of the synthetic block can be effectively compensated, a homogenous and stable pressure field can be provided to the growth of the diamond, the internal virtuality of the graphite column can be prevented, safety and reliability can be realized, the product yield and quality can be greatly improved, and the proportion of excellent crystal of the diamond product can be improved from 30 percent to 38 percent.
Description
Technical field
The utility model belongs to the superhard material synthesis technical field, particularly a kind of interior 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 provides a kind of simple in structure, pressure field stable and uniform, can effectively prevent interior 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: supercharging diamond synthesis block in a kind of, 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 the pyrophyllite sheet between the graphite post half block butt joint end face; Graphite post half block and pyrophyllite sheet middle part axially are provided with cavity, are equipped with the pyrophillite rod in the cavity.
Described pyrophyllite sheet and graphite post half block end face equal and opposite in direction.
Described pyrophyllite rod two ends are mutually concordant with graphite post half block end face.
Be provided with insulation component between described heating element heater and the graphite post half block.
Compared with prior art, the utility model has the advantages that:
1, the graphite post of synthetic piece is made of two graphite post half blocks of end face butt joint, is provided with the pyrophyllite sheet between the graphite post half block butt joint end face; Graphite post half block and pyrophyllite sheet middle part axially are provided with cavity, be equipped with the pyrophillite rod in the cavity, form the uniformly interior supercharging assembling mode of pressure field, simple in structure, because the pyrophyllite pressure transmission is functional, pyrophyllite rod and pyrophyllite sheet can play the effect of the pressure transmission to all the winds from the centre under the superhigh-temperature and-pressure condition, can effectively remedy synthetic piece internal pressure deficiency, synthetic piece internal pressure is evenly distributed, provide an even and pressure stable field to growth of diamond, prevent in the graphite post empty, safe and reliable, can improve product yield and quality greatly, the excellent brilliant ratio of diamond product is brought up to about 38% from 30%.
2, the utility model can prolong the service life of cubic hinge press synthesis device and auxiliary accessories thereof, reduces synthetic cost, and is safe and reliable.
