Abstract
The utility model discloses a composite conductive steel ring for the synthesis of a superhard material, including a conductive steel ring and characterized in that the upper end of the conductive steel ring is equipped with a metal ring structure so that during the synthesis of a synthetic diamond, a cubic boron nitride single crystal and polycrystalline product, the special composite conductive steel ring transmits large current into the synthesis reaction room and a high voltage leakage accident can be avoided because the composite steel ring does not melt easily.
Description
Affiliated technical field
Device when the utility model relates to synthesizing superhard material under a kind of high-temperature and high-pressure conditions specifically relates to the composite conducting steel ring of the synthetic usefulness of a kind of superhard material.
Background technology
At present, synthesizing cubic boron nitride and diamond are finished under high-temperature and high-pressure conditions, the voltage that the outside provides makes the resistance heating of reative cell internal heat generation material produce high temperature by conducting steel ring, reative cell produces the growth conditions that high temperature has satisfied cubic boron nitride and diamond, but high temperature end face generation that conducting steel ring contact with reative cell is simultaneously melted to some extent, is unfavorable for the growth of crystal or accidents caused.
Summary of the invention
The purpose of this utility model just is to provide a kind of conducting steel ring of avoiding directly to contact with reative cell, is beneficial to the composite conducting steel ring of the growth of crystal and the synthetic usefulness of superhard material that the minimizing accident takes place.
The purpose of this utility model can realize by following measure:
The utility model comprises conducting steel ring, is provided with becket in the upper end of conducting steel ring.
The hollow diameters of the becket in the utility model is less than the hollow diameters of conducting steel ring, and certainly, the hollow diameters of becket also can equal the hollow diameters of conducting steel ring.In addition, conducting steel ring and becket can be integral structure or separate type.Be provided with insulation in the conducting steel ring and add core, the top that core is added in insulation is a boss.
The utility model is owing to adopt the structure that becket is set in the upper end at conducting steel ring, make when synthesis of artificial diamond, cubic boron nitride monocrystal and polycrystalline goods, by the specific complex conducting steel ring when the synthetic reaction chamber interior is carried big electric current, this composite steel rim is difficult for fusing, thereby has avoided high pressure leakage accident to take place as far as possible.
Description of drawings
Accompanying drawing is a schematic diagram of the present utility model
The specific embodiment
As shown in the figure: the utility model comprises conducting steel ring 2, is provided with becket 1 in the upper end of conducting steel ring.The hollow diameters of becket 1 is less than the hollow diameters of conducting steel ring 2.Be provided with insulation in the conducting steel ring 2 and add core 3, the top that core 3 is added in insulation is a boss.Becket 1 promptly is enclosed within insulation to be added on the boss of core 3.
Operation principle of the present utility model is as follows: the utility model purpose is that conducting steel ring is not directly contacted with reative cell, add a refractory metal ring at them, conducting steel ring end face temperature is unlikely to reach fusion temperature like this, make the contact resistance of electric conductor not produce sudden change, thereby make the electric current that passes through in the reative cell not cause big variation.The composite conducting steel ring that the utility model uses as shown in the figure, 1 for refractory metal approaches annulus, the 2nd, the bottomed cylindrical shape conducting steel ring of steel, the 3rd, core is added in insulation, insulation, pressure transmission.The width of becket 1 should can not separate less than the thickness of steel ring 2 in actual the use, can cast yet or melt together.
Claims (3)
1, the composite conducting steel ring of the synthetic usefulness of a kind of superhard material, it comprises conducting steel ring (2), it is characterized in that: be provided with becket (1) in the upper end of conducting steel ring (2).
2, the composite conducting steel ring of the synthetic usefulness of superhard material according to claim 1, it is characterized in that: the hollow diameters of described becket (1) is less than the hollow diameters of conducting steel ring (2).
3, the composite conducting steel ring of the synthetic usefulness of superhard material according to claim 1 is characterized in that: be provided with insulation and add core (3) in described conducting steel ring (2), the top that core (3) is added in insulation is a boss.
