Abstract
The utility model discloses a novel assembling structure of a superhard material synthesis chamber; a carbon tube and a carbon sheet are arranged outside a superhard material test bar; a metal conductive ring is arranged on the external side of the carbon sheet; a shielding layer is arranged on the external side of the carbon tube; a heat insulation layer is arranged between the shielding layer and an outermost pyrophyllite block; and the heat insulation layer extends to the metal conductive ring on the external side of the carbon sheet; through the adoption of the novel assembling structure disclosed by the utility model, heat losses at two ends of a heating direction are reduced and growth consistency of crystals in the chamber is promoted, so that product quality is improved.
Description
Technical field
The utility model relates to superhard material high pressure synthesis technical field, especially relates to the new-type package assembly of a kind of superhard material synthetic cavity.
Background technology
At present, in superhard material is synthetic, be pressed into cylindric coupon after the raw material that diamond or cubic boron nitride are synthetic and catalyst mix and put into heating tube, the cylinder that reinstalls pyrophyllite block is behave affectedly in the body, conducting strip is placed at two ends again and conducting steel ring forms complete high-pressure chamber assembled block, assembled block is put into the high-pressure work cavity of cubic hinge press, pressurize and set up super-pressure by being contained in six top hammers on the movable cylinder, simultaneously pass into electric current in the conducting steel ring direction and heat, thereby foundation is fit to the condition of the high pressure high temperature of superhard material growth.In the existing package assembly, the heat loss at heating direction (being called axially) two ends is more, and causes axial-temperature gradient larger, affects the distribution of chamber pressure temperature, thereby affects the uniformity of crystal growth in the cavity.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of superhard material synthetic cavity new-type package assembly, reduces the heat loss at heating direction two ends, improves the uniformity that promotes crystal growth in the cavity, thereby improves the quality of products.
For achieving the above object, the utility model by the following technical solutions:
The new-type package assembly of superhard material synthetic cavity of the present utility model is, carbon pipe and carbon plate are set outside the superhard material coupon, the carbon plate arranged outside has the metallic conduction circle, at described carbon pipe arranged outside screen layer, between the pyrophyllite block of screen layer and outermost heat-insulation layer is set, heat-insulation layer extends to the metallic conduction circle in the carbon plate outside.
Further, described screen layer adopts magnesia or dolomite material, and described heat-insulation layer adopts dolomite material.
Further, described metallic conduction loop diameter is 6-10mm.
The beneficial effects of the utility model are:
The structure that the utility model adopts is to improve on the basis of original synthetic package assembly to form, guarantee around coupon, to form some equally distributed housings, at first coupon is outer is wrapped to form screen layer by magnesia or dolomite cup and sheet, avoid cavity material to participate in conductive heater directly for diamond is synthetic like this, thereby guarantee the uniformity of cavity resistance, and the synthetic heating carbon pipe of can isolating of cubic boron nitride is on synthetic impact, inferior periphery is wrapped to form heat-insulation layer by dolomite bushing pipe and sheet, outermost forms the pressure transmission sealant by pyrophyllite block, reduce the diameter of conducting steel ring in the heating direction as far as possible, can reduce the direct losses of heat, reach good heat insulation effect, thereby help to improve the quality of products.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, take a hint.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in drawings, the new-type package assembly of superhard material synthetic cavity of the present utility model is characterised in that, at superhard material coupon 7 outer carbon pipe 4 and the carbon plates 2 of arranging, carbon plate 2 arranged outside have metallic conduction circle 1, at described carbon pipe 4 arranged outside screen layers 6, between the pyrophyllite block 5 of screen layer 6 and outermost heat-insulation layer 3 is set, heat-insulation layer 3 extends to metallic conduction circle 1 place in carbon plate 2 outsides.Described screen layer 6 adopts magnesia or dolomite material, and described heat-insulation layer 3 adopts dolomite material.Described metallic conduction loop diameter is 6-10mm.
In the present embodiment, the metallic conduction loop diameter is 10mm.Because the diameter of metallic conduction circle is very little, the heat-insulation layer that dolomite material is made extends to the conductive ring place always, so just greatly reduced the heat loss at heating direction (being called axially) two ends, reduce axial-temperature gradient to the impact of chamber pressure Temperature Distribution, thus so that the uniformity raising of crystal growth in the cavity.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
