The utility model is characterized in that a dolomite liner tube and a dolomite ring are nested in the inner wall of a sleeve cavity which is synthetized by pyrophyllite blocks; insulating layers are arranged on the inner wall and at the upper end and the lower end of the liner tube, and core columns by crystal seed synthesis are arranged in the insulating layers; the dolomite ring is positioned between the insulating layers which are arranged at the upper part and the lower part of the liner tube and a conducting metal sheet, so that a heating cavity can be formed; a heating sheet is arranged in the heating cavity, and conducting rings which are contacted with the conducting metal sheet are arranged on the inner wall at both ends of the sleeve of the pyrophyllite blocks. Compared with the prior art, the high grade diamond which is formed by adopting the high grade diamond forming structure by crystal seed synthesis has the advantages of good crystal form, high transparency, powerful heat impact toughness, etc.
Description
Technical field:
The utility model belongs to the synthetic facility technology field of diamond, is the synthetic high grade diamond generating structure of a kind of crystal seed.
Background technology:
Diamond also claims carbonado, be with manual method make at present known to the hardest material of occurring in nature, China is the big country that diamond is produced, but the diamond product grade focuses mostly at low and middle-grade times, and the high grade artificial diamond of high profit goes back dependence on import at present.In technique known, the catalyst that low and middle-grade times diamond 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, little power consumption and be better than the synthetic high grade diamond generating structure of common artificial adamantine crystal seed aspect crystal formation, transparency, the thermal shock toughness.
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, heating plate, its main feature is: at the synthetic sleeve cavity wall of pyrophyllite in lumps, be nested with the dolomite bushing pipe, the white clouds stone ring, the inwall and the upper and lower end parts of bushing pipe are provided with separation layer, the built-in synthetic stem stem of crystal seed that is placed with of separation layer, between the separation layer and conductive metal sheet at white clouds stone ring position about bushing pipe, and constitute heating cavity thus, the built-in heating plate that is placed with of cavity, conductive ring is arranged on pyrophyllite in lumps sleeve lining two ends, and contacts with conductive metal sheet.
The generating structure of the synthetic high grade diamond of the crystal seed of making according to such scheme, with 105 blocks of synthetic diamonds is example, handling, showing in the sorting, result, per unit area yield reaches 39.3ct, synthetic diamond grit reaches 70% at 40/60 content, the above diamond content of 40/60 granularity SMD level reaches 32.3%, and the above content of SND30 level reaches 12%.And adamantine color is golden yellow, underbead crack, bubble seldom, no hoary hair's diamond, per unit area yield is higher, and all is significantly increased on indexs such as monocrystalline percentage of head rice, high-strength ratio, impact strength.Compared with prior art, the high grade diamond that adopts the utility model to generate has advantages such as crystal formation is good, transparency is high, thermal shock toughness is strong.
Utilize accompanying drawing to further describe embodiment of the present utility model below.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, the utlity model has the synthetic sleeve chamber 1 of pyrophyllite in lumps, conductive ring 2, heating plate 8, at pyrophyllite in lumps sleeve chamber 1 inwall, be nested with dolomite bushing pipe 5, white clouds stone ring 4, the inwall and the upper and lower side of bushing pipe 5 are provided with separation layer, the built-in synthetic stem stem 9 of crystal seed that is placed with of separation layer, for improving diamond product grade, the synthetic stem stem 9 of crystal seed adopts Nano diamond as crystal seed, and cooperate with rational proportion with powder catalyst alloy powder, high purity graphite powder, mix by doing, granulation, suppression process constitute.Separation layer is to be made of sheet iron strip (steel pipe) 6 and stalloy 7, white clouds stone ring 4 is between the separation layer and conductive metal sheet 3 at bushing pipe position about in the of 5, what conductive metal sheet 3 adopted is stainless steel substrates, constitute heating cavity by stalloy 7 and conductive metal sheet 3 by white clouds stone ring 4, the built-in heating plate 8 that is placed with of cavity, heating plate 8 is to be made of graphite flake, and conductive ring 2 is arranged on 1 inwall two ends, pyrophyllite in lumps sleeve chamber, and contacts with conductive metal sheet 3.After pressing the said structure assembling, through 130 ℃ ± 5 ℃ insulations 36 hours, synthetic high grade diamond promptly was available on the machine.
