Abstract
An external indirect heating type diamond synthesizing block belongs to the technical field of diamond composition, comprising a diamond synthesizing pole with two ends provided with composite conductive heat-proof apparatuses. The outboards of the synthesizing pole and the composite conductive heat-proof apparatus are provided with sealing pressure-conducting medium. A heating element, a heat-transfer element, and an isolating element are sequentially arranged between the sealing pressure-conducting medium and the composite conductive heat-proof apparatus from outer to inner. The utility model can synthesize high-grade diamonds in large amount with high factor of merit and low manufacturing cost.
Description
Technical field
The utility model belongs to the diamond synthesis technical field, particularly a kind of outer indirect heating diamond synthesis block.
Background technology
The diamond synthesis block structure of using in the diamond building-up process as shown in Figure 1, comprise diamond synthesizing column 11, synthetic post 11 two ends are provided with composite conducting heat-proof device 1, the sealing medium cylinder 4 of synthetic post 11 and the sheathed embedded transmission medium cylinder 3 in composite conducting heat-proof device 1 outside, transmission medium cylinder 3 embed among the sealing medium cylinder 4 interior eaves.Should belong to direct-heating type by synthetic piece mode of heating, electric current itself generates heat by synthetic post 11.Adopt above-mentioned synthetic piece to carry out that diamond is synthetic to exist following technical problem: (1) required electric current is big, causes the energy consumption height, and the hammer consumption is big; (2) synthetic column temperature inhomogeneous-center height, peripheral low, cause diamond film inhomogeneous; (3) in the course of reaction along with synthetic column material changes, cause size of current to change, influence the stability of diamond film.
The utility model content
The outer indirect heating diamond synthesis block that provides a kind of synthetic effect good is provided the utility model purpose
For reaching above-mentioned purpose, the utility model adopts following technical scheme: outer indirect heating diamond synthesis block, comprise diamond synthesizing column, synthetic post two ends are provided with the composite conducting heat-proof device, the synthetic post and the composite conducting heat-proof device outside are arranged with hermetical and pressure madium, are disposed with heater element, heat transfer insulation component and isolated component between hermetical and pressure madium and composite conducting heat-proof device and the synthetic post certainly outside to inside.
Heater element, heat transfer insulation component and isolated component are the pipe of closed at both ends.
Heater element is made up of the graphite disk at graphite pipe and covering pipe two ends; The heat transfer insulation component is formed by the alkaline earth oxide pipe fastening of two one end sealings; Isolated component is made up of the metal disk of metal circular tube and covering pipe.
In the utility model, heater element, heat transfer insulation component thickness are 1-5mm, and the heater element effect is a conductive exothermal, and the effect of heat transfer insulation component is to conduct heat and electric insulation, isolated component thickness 0.1-1.0mm, and its effect is to prevent that synthetic post from being polluted by foreign matter.Heater element, heat transfer insulation component and isolated component are the pipe of closed at both ends from a structural point, can adopt kinds of processes to process.For example, for heater element, available extrusion is made the graphite pipe, is formed at two ends covering graphite disk; Also can be wound into the graphite pipe, form at two ends covering soft graphite disk again with flexible graphite paper.For the heat transfer insulation component, can be processed into the alkaline earth oxide pipe earlier, form at two ends covering alkaline earth oxide disk again; The alkaline earth oxide pipe that also can directly be processed into two one end sealings fastens and forms.
Utilize the utility model to carry out diamond and synthesize, change the direct mode of heating in original inside into outside indirect mode, electric current no longer passes through synthetic post, but by peripheral heater element ecto-entad heat transfer.This mode of heating has changed the low inside and high outside situation of synthetic column temperature effectively, and internal and external temperature distributes and is tending towards evenly can significantly improving adamantine output and quality; Heating current reduces, and not only saves electric energy, the more important thing is the hammer consumption that has reduced hard alloy top hammer, and adamantine production cost is minimized; Effectively prevent the variation of heating current, helped the stable growth gem grade diamond; Being provided with of separation layer can prevent that synthetic post from being polluted by the material of outside, for diamond film provides a clean environment, and diamond synthesis purity height.
Utilizing in the utility model synthetic piece, is example with 38 millimeters synthetic posts of diameter, and the diamond per unit area yield is brought up to more than 80 carats by original 60 carats, and the gem grade diamond ratio is brought up to about 40% by original 20%～30%, and the diamond cost reduces about 30%.
The utility model is applicable to the various cubic hinge press that China diamond manufacturer uses (comprise traditional have cylinder press and novel no cylinder press), also is applicable to the belt type press that European and American countries extensively adopts.
