Description
Technical field
The utility model relates to a kind of assembly for the synthesis of superhard material, belongs to superhard material (diamond, cubic boron nitride etc.) and synthesizes the field.
Background technology
Diamond, two kinds of superhard materials of cubic boron nitride be owing to having the combination properties such as excellent mechanics, calorifics, optics, electricity and chemistry, and be widely used in the fields such as machining, building materials, oil exploitation.Current, synthetic HTHPs that adopt of diamond, cubic boron nitride static synthetic more, provide the equipment of high-temperature and high-pressure conditions to mainly contain cubic hydraulic press and top, two sides hydraulic press, carrying out superhard material when synthetic, the synthetic post of diamond synthesizing column or cubic boron nitride is placed in the cavity as the assembly of the synthetic piece of regular hexahedron of sealing medium.
Originally the synthesizing superhard material relies on the resistance heating (being called direct heating system) of synthetic post itself, and the electric current that needs is very high, and synthesis device is easy to ' blowing out ' and causes that nail hammer is broken, and production cost is higher, and the economic benefit of enterprise is lower.Now the synthesizing superhard material relies on graphite flake and the heating of graphite-pipe exothermic material (be called indirect system), greatly reduce resultant current with relying on the resistance heating contrast of synthetic post own, at present, the composite structure 98% of synthesis of artificial diamond adopts graphite paper indirect system (graphite-pipe thickness is in the 0.9mm left and right), adopt the oxidation cup as insulating materials, only have only a few to adopt direct heating system to synthesize.Use direct heating system power consumption than the power consumption of indirect structure large 1/3, when synthesizing simultaneously, the temperature on nail hammer surface is higher, the stability of press and the quality of nail hammer have been proposed very high requirement, and the nail hammer loss is generally 3 times of the indirect system, so only have only a few producer to use.
The below does simple introduction to existing employing graphite flake and graphite-pipe exothermic material as the assembly for the synthesis of superhard material of the indirect of heater, referring to Fig. 3, comprise the pyrophyllite composite block 1 with cavity, successively be symmetrically arranged with conductive steel cap 2, pyrophillite ring 3, insulation transmission medium white clouds stone ring 4, exothermic material graphite flake 5 from the end to described cavity center position at the two ends of described cavity; Be provided with exothermic material graphite-pipe 62 between two described graphite flakes 5, be arranged with successively insulating materials magnesia cup 7, shielding material iron cup 8 from described graphite-pipe 62 inboards, described iron cup 8 inner hollow chambeies arrange the synthetic post 9 of superhard material that the growth superhard material is used.
Although the synthesizing superhard material relies on graphite flake and the heating of graphite-pipe exothermic material now, compare with the synthetic resistance heating of post of dependence own and greatly reduce resultant current, but because the resistance of graphite flake and graphite-pipe is less, slow so heat up, generated time is longer, quality requirement to pyrophyllite composite block is higher, and the thickness of graphite flake is at 2mm, the thickness of graphite-pipe is in the 1mm left and right, thereby cause synthetic cavity in the situation that same pyrophyllite composite block foreign side dwindles larger, affect the output of synthesizing superhard material, the economic benefit of enterprise increases little relatively.
