Abstract
The utility model provides a powder accelerant structure of synthesizing high grade diamond to the technical field of synthesis and preparation of diamond. The utility model is mainly characterized in that a dolomite liner tube is nested in the inner wall of a sleeve barrel cavity which is synthesized by pyrophyllite blocks, the central part of the sleeve barrel cavity of pyrophyllite blocks is arranged with a graphitic synthetic button stem, the external surface of the graphitic synthetic button stem is arranged with an isolated layer, the upper end and the lower end are arranged with electric sheet metals and dolomite rings, wherein the isolated layer and the electric sheet metals are separated into a cavity body through the dolomite rings, a heating plate is arranged in the cavity body, and electric circles are arranged on two ends of the inner wall of the sleeve barrel of the pyrophyllite blocks and are connected with the electric sheet metals. Compared with prior art, due to the adoption of the utility model, the indexes on monocrystal intact rate, high strength ratio and impact strength of synthetical diamond are all improved over once, and the synthesizing power is relatively low. Compared with flaky accelerant and the cavity body, electric power consumption can be saved by one third to one half.
Description
Technical field:
The utility model belongs to the diamond synthesis technical field, is a kind of powder catalyst structure of synthetic high grade diamond.
Background technology:
In technique known, the catalyst that diamond synthesis is used is the sheet alloy material, carbon source is the graphite flake that processes after electrographiteization, catalyst, graphite flake clean up and drying after alternately pack in the synthetic chamber of pyrophyllite, conducting steel ring is loaded onto at two ends, more than 10 hours, can on cubic hinge press, go out diamond through 140 ℃ ± 5 ℃ insulations through high temperature, high pressure synthetically grown.The problem that the slice catalyst diamond synthesis exists is: diamond grit is 40/45～70/80, and color is a yellow green, and underbead crack, bubble are more, and poor transparency has hoary hair's diamond, and resistance to compression, impact strength are very low, and output is lower, and power consumption is big.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can improve resistance to compression, shock resistance, and quality is good, output is high, the powder catalyst structure of the synthetic high grade diamond of little power consumption.
Realize that the technical scheme that the purpose of this utility model is taked is improved on the basis of original slice catalyst diamond synthesis, it has the synthetic sleeve chamber of pyrophyllite in lumps, conductive ring, graphite flake, its main feature is: at pyrophyllite in lumps sleeve cavity wall, be nested with the dolomite bushing pipe, the centre in pyrophyllite in lumps sleeve chamber is provided with synthetic stem stem, the outer surface of synthetic stem stem is provided with metallic spacer, the upper and lower end parts of separation layer is provided with conductive metal sheet and white clouds stone ring, wherein, be divided into cavity by the white clouds stone ring between separation layer and the conductive metal sheet, the built-in heating sheet that is placed with of cavity, conductive ring is arranged on pyrophyllite in lumps sleeve lining two ends, and contacts with conductive metal sheet.
According to the powder catalyst structure that is used for synthetic high grade diamond that such scheme is made, its synthetic diamond grit is 40/45～45/50, and granularity is more concentrated, color is golden yellow, underbead crack, bubble seldom, transparency is good, no hoary hair's diamond, per unit area yield is higher.Compared with prior art, adopt the utility model structure, synthetic diamond is all improved more than 1 times in monocrystalline percentage of head rice, high-strength ratio, impact strength index, synthetic power is lower, compares with cavity with slice catalyst, and power consumption saves 1/3～1/2.
Utilize accompanying drawing to further describe embodiment of the present utility model below.
