Description
Technical field
The utility model belongs to superhard material synthesis technical field, particularly a kind of Novel diamond synthesis block.
Background technology
Adamantine composition principle is: by diamond synthesis block is pressurizeed, heated, graphite column is completed by graphite to adamantine transformation.Diamond synthesis block is the key factor that affects diamond product quality, and traditional diamond synthesis block is made up of graphite column, conducting steel ring, heating element heater and pyrophyllite block etc.When energising, make heating element heater heating by conducting steel ring, heat, through reaching graphite column with the insulating barrier of heating element heater close contact, makes graphite be converted into diamond under superhigh-temperature and-pressure.
Along with the development that diamond synthesis press maximizes, diamond synthesis block also expands thereupon, and the energy that in synthetic cavity, graphite column needs is just more and more higher.But the package assembly of diamond synthesis block does not but change, and causes in diamond building-up process thereupon, the low conversion rate of graphite, synthetic cavity outwards heat radiation is too fast, too much, and " venting big gun " phenomenon increases, and causes economic benefit significantly not promote along with the expansion of synthetic cavity.
Utility model content
The purpose of this utility model be to provide a kind of rational in infrastructure, graphite transform is high, high insulating effect and can effectively stop the Novel diamond synthesis block that " venting big gun " phenomenon occurs.
For achieving the above object, the technical solution of the utility model is: a kind of Novel diamond synthesis block, and comprise the heating plate at graphite column, graphite column two ends and be set in the cartridge heater of graphite column excircle, between graphite column and heating plate, cartridge heater, be provided with core insulator; On heating plate outer face, be provided with successively conductive tube, conducting strip and square-cap type conductive steel ring, conductive tube and heating plate outer face join, and conductive tube and square-cap type conductive steel ring difference apical grafting are on outer and the interior edge of conducting strip; Square-cap type conductive steel ring and cartridge heater are arranged with pyrophyllite in lumps outward, and conductive tube and square-cap type conductive steel ring inside are provided with dolomite cake, are provided with successively from outside to inside pyrophillite ring and white clouds stone ring between conductive tube, square-cap type conductive steel ring and pyrophyllite in lumps.
Between described core insulator and graphite column, be provided with air-breathing metal level.
Described pyrophyllite block inwall and cartridge heater corresponding part offer groove, are provided with dolomite clinker in groove.
Described pyrophyllite block end face and side are provided with boss.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises the heating plate at graphite column, graphite column two ends and is set in the cartridge heater of graphite column excircle, between graphite column and heating plate, cartridge heater, is provided with core insulator, on heating plate outer face, be provided with successively conductive tube, conducting strip and square-cap type conductive steel ring, conductive tube and heating plate outer face join, and conductive tube and square-cap type conductive steel ring difference apical grafting are on outer and the interior edge of conducting strip, square-cap type conductive steel ring and cartridge heater are arranged with pyrophyllite in lumps outward, conductive tube and square-cap type conductive steel ring inside are provided with dolomite cake, conductive tube, between square-cap type conductive steel ring and pyrophyllite in lumps, be provided with successively from outside to inside pyrophillite ring and white clouds stone ring, it is rational in infrastructure, conduct heat evenly, conductive tube, conducting strip and square-cap type conductive steel ring form low heat conduction composite conducting plug, can effectively stop the heat in synthetic cavity outwards to scatter and disappear, save electric energy, high insulating effect, make temperature field more balanced, be conducive to improve the quality of products, can greatly improve graphite transform, thereby effectively improve per unit area yield, and can effectively stop the generation of " venting big gun " phenomenon.
2, pyrophyllite block end face and side are provided with boss, can make the pressure utilization rate of cubic apparatus synthesis press increase, and improve the compression ratio of graphite column in synthetic cavity, thereby are beneficial to raising graphite transform.
3, between core insulator and graphite column, be provided with air-breathing metal level, in diamond building-up process, air-breathing metal level can absorb the air and the Yin Gaowen that after diamond synthesis block is compressed by press, are sealed in synthetic cavity makes the carbon dioxide of dolomite decomposition generation, thereby avoids the generation of diamond release post-synthesis phase " venting big gun ".
