Abstract
The invention discloses a composite crucible for the growth of sapphire crystals. The composite crucible consists of a crucible main body and a lengthened crucible tube wherein the crucible main body and the lengthened crucible tube are sleeved with each other through a positioning fitting surface, and the positioning fitting surface adopts cylindrical surface sleeving or conical surface sleeving. The composite crucible disclosed by the invention has the following beneficial effects: the crucible is of an upper and lower composite structure; the crucible main body is connected with the lengthened crucible tube through the positioning fitting surface; the positioning fitting surface is a cylindrical surface or conical surface; the crucible main body has normal service life and the lengthened crucible tube can be used repeatedly, thus the comprehensive service life of the crucible can be increased and the production cost can be reduced; and the composite crucible has a simple structure and is easy to prepare and convenient to use.
Description
Technical field
The invention belongs to crystal and prepare equipment technical field, relate to a kind of sapphire crystal growth composite crucible.
Background technology
In the sapphire crystal growth system, crucible is vital parts, and the sapphire starting material after the heat fused, carry out sapphire crystal growth under the guiding of seed crystal in crucible; Because slowly carry out sapphire crystal growth (more than 2000 ℃), long-time (more than 10 days) under hot environment, therefore, require crucible can be high temperature resistant, long lifetime, low cost; Because the liquid sapphire raw material after the fusing is in the middle and lower part of crucible, thus tend to cause the crucible middle and lower part to occur loss, cracking, disrepair phenomenon more easily, thus cause whole crucible to scrap.Crucible of the prior art is the cylindrical crucible structure, in the sapphire crystal growth process, will cause integral body to scrap in case the crucible middle and lower part is damaged, thereby increase production cost.
Summary of the invention
The purpose of this invention is to provide a kind of sapphire crystal growth composite crucible, solved cylindrical crucible structure of the prior art, because loss, cracking, disrepair phenomenon appear in the crucible middle and lower part, thus the problem that causes whole crucible to scrap.
The technical scheme that the present invention adopted is, a kind of sapphire crystal growth composite crucible is made up of crucible main body and lengthening crucible tube, and crucible main body and lengthening crucible tube are through locating the mating surface socket.
The invention has the beneficial effects as follows, be set to composite structure up and down through crucible, the crucible main body links together through location mating surface and lengthening crucible tube; The location mating surface is cylindrical surface or cone surface; The crucible main body realizes normal work-ing life, and the lengthening crucible tube can be repeatedly used, thereby reduces production costs the comprehensive work-ing life of improving crucible; Simple in structure, easy to manufacture, easy to use.
Description of drawings
Fig. 1 is the loading synoptic diagram of solid feed in crucible embodiment 1 working process of the present invention;
Fig. 2 is the view after raw material melts in crucible embodiment 1 working process of the present invention;
Fig. 3 is the socket mode structural representation of crucible embodiment 2 of the present invention when wall thickness is thin.
Among the figure, 1. the crucible main body is 2. located mating surface, 3. lengthening crucible tube, 4. solid feed, 5. liquid raw material.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
As shown in Figure 1, the structure of composite crucible of the present invention is, is made up of crucible main body 1 and lengthening crucible tube 3, and crucible main body 1 is consistent with the material of the crucible tube 3 that extends; Crucible main body 1 links together through location mating surface 2 sockets with lengthening crucible tube 3.
With reference to Fig. 1, Fig. 2, for the thicker crucible of wall thickness,, constitute location mating surface 2 by inner convex platform, outer lug boss through the inner convex platform of lengthening crucible tube 3 lower port and the outer lug boss socket of crucible main body 1 upper edge, realize socket.
With reference to Fig. 3, for the thin crucible of wall thickness,, constitute location mating surface 2 by inner convex platform, inner headed face through the inner convex platform of lengthening crucible tube 3 lower port and the direct socket of inner headed face of crucible main body 1 upper edge, realize socket.
Composite crucible of the present invention in the course of the work; Earlier solid feed is loaded into the upper edge height of lengthening crucible tube 3; Then; Continuous thawing along with raw material; Be in when the real solution plane after whole thawings within the splendid attire capacity of crucible main body 1; Crucible main body 1 is born bigger working load; When loss, cracking, disrepair phenomenon appear in the crucible main body; Can normally change; Realize normal work-ing life; The lengthening crucible tube then can be repeatedly used, and has significantly lowered the replacement cycle of lengthening crucible tube, and the effect that reduces cost is obvious.
Composite crucible of the present invention, simple in structure, easy to manufacture, easy to use, can be widely used in sapphire crystal growth system, solar energy silicon single crystal growing system, laser crystal growth system and other high temperature crystal growth system.
