The superhard material synthesis block assembly element has the positive and beneficial effects that the heat insulation effect is improved, the synthesis current is reduced, the synthesis cost of superhard materials is effectively reduced, the heat generation quantity of the combined part of the conducting steel rings and the heating body during the electrification is reduced, the melting possibility of the steeling rings is reduced, and the conductance can be improved, so the synthesis temperature control of artificial diamond, elboron and polycrystal products is more stable, and the sealing performance and the safety during the synthesis of the superhard materials are greatly improved.
Description
Technical field
[0001] the utility model relates to the synthetic field of superhard material, is specifically related to the synthetic piece assembly of a kind of superhard material.
Background technology
Current, China has become world superhard material big producing country, progressively drive ons boldly to world powers.Diamond, cubic boron nitride are two kinds of the highest superhard materials of world hardness, because it has excellent combination properties such as mechanics, calorifics, optics, electricity and chemistry, have been widely used in various fields such as machining, building materials, oil exploitation.It is static synthetic that the production of existing diamond and cubic boron nitride mostly is HTHP, adopt cubic hinge press or belt type press device fabrication to go out required high-temperature and high-pressure conditions, carrying out superhard material when synthetic, raw material, catalyst are loaded in the regular hexahedron as sealing medium and synthesize in the hollow cavity of piece, two ends install conducting steel ring additional and are sealed, energising heating simultaneously and pressurization.Contact site at conducting steel ring and calandria need be provided with the conductive heat insulation layer, and its effect has two: one, prevents that conducting steel ring from directly contacting with heater, meets high temperature melting, and then the ablation hard alloy top hammer; The 2nd, prevent outwards a large amount of the scattering and disappearing of heat in the synthetic chamber.But in the synthetic piece assembly of existing superhard material, be conductive heat insulation layer or conductive heat insulation material how with Titanium circle and/or pure titanium sheet, yet titanium is very rare valuable heavy metal, its price is high naturally, and then caused the synthetic cost of superhard material high, under the situation that competition is growing more intense in the superhard material industry, this situation presses for and gets a new look.
Summary of the invention
The technical problems to be solved in the utility model provides the synthetic piece assembly of a kind of superhard material, to solve the too high technical problem of synthetic cost of superhard material.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of superhard material synthesizes the piece assembly, comprise the pyrophillite pressure transmission piece of being with cavity, the cavity two ends are symmetrically arranged with conducting steel ring successively therein, core, thermal insulation layer are filled out in the pyrophillite insulation, between two thermal insulation layers, be provided with the graphite heating pipe, this graphite heating pipe inboard is followed successively by insulation tube, the synthetic piece of raw material, and described thermal insulation layer is the graphite ply of paper; Between described graphite heating pipe and conducting steel ring, be provided with the graphite paper ring.
The thickness of described graphite paper is 0.2～1.8 mm.
Described graphite paper sulfur content≤200ppm.
Density 0.1～the 1.5g/cc of described graphite paper.

3Ohmcm.
The utlity model has actively useful effect:
1. improve heat insulation effect, reduced resultant current, effectively reduced the synthetic cost of superhard material;
2. the caloric value when reducing the energising of conducting steel ring and calandria binding site reduces the possibility that steel ring melts;
3. can improve electrical efficiency, make the synthesis temperature control of diamond, cubic boron nitride and polycrystalline goods more stable;
4. sealing and security when superhard material is synthetic have been improved greatly.
