Abstract
A double-crucible device for growing single crystals through induction heating physical vapor phase transfer belongs to the technical field of single crystal growth and particularly relates to a device for growing the single crystals through induction heating physical vapor phase transfer. The double-crucible device comprises a heat preservation drum; an outer crucible is arranged in the heat preservation drum; an inner crucible is arranged in the outer crucible; and single crystal raw materials and seed crystals are arranged in the inner crucible. Compared with the prior art adopting a single crucible, the device has the advantages that the consumption of crucible materials with high melting points can be greatly reduced, and when the inner crucible is taken out, a heat preservation material can not be scraped off, thereby the service life of the heat preservation material is prolonged.
Description
Technical field
The invention belongs to the single crystal growing technical field, particularly relate to the device of induction heating physical vapor transmission growing single-crystal.
Background technology
During induction heating physical vapor transmission method growing single-crystal, need to use materials with high melting point (for example: high purity graphite, metal tantalum, tungsten etc.) to make crucible, be used for splendid attire material source (being placed at the bottom of the crucible) and seed crystal (being contained in the crucible interior surface).Generally all be with a crucible (being designated hereinafter simply as " single crucible ") at present, not only made heating element, but also made growth chamber, relatively simple for structure.But in order to satisfy the requirement of heating and temperature, the crucible size that the size of single crucible need be done more requiredly than simple charging is a lot of greatly, and when taking out the monocrystalline that generates, generally can only destroy crucible.Therefore, single crucible can only disposablely use, and this causes, and the consumption of HMP crucible material is big, the crucible cost is high.In addition, single crucible come out of the stove at every turn the time rub the lagging material that some are close to its outer wall easily, need replenish during shove charge once more, even process heat-preservation cylinder again.
Summary of the invention
The technical problem that the present invention will solve is to overcome the disposable use of crucible, the defect of high cost that existing single crucible causes, and a kind of pair of crucible device is provided, and outer crucible wherein can repeatedly use, and easy to operate, cost reduces.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The device of a kind of pair of crucible induction heating physical vapor transmission growing single-crystal comprises heat-preservation cylinder, in said heat-preservation cylinder, is provided with outer crucible, in said outer crucible, is provided with interior crucible, and crystal raw material and seed crystal are positioned at crucible.
Crucible is provided with the crucible lid that is used to place seed crystal in said.
The present invention is applicable to the method for all induction heating physical vapor transmission method growing single-crystals, includes but not limited to silit, aluminium nitride AlN.
Apparatus of the present invention are to realize its function like this: during induction heating physical vapor transmission method growing single-crystal, use the co-axial materials with high melting point crucibles of inside and outside two covers (abbreviation " two crucible "), outer crucible is in order to satisfy the requirement of heating and temperature field, and size is bigger; Interior crucible only is used for splendid attire raw material (being placed at the bottom of the crucible) and seed crystal (being contained in the crucible interior surface), and size is less.Interior crucible is placed on the outer crucible bottom coaxially, and two crucibles all have the crucible lid to seal separately, and perhaps outer crucible also can not add the crucible lid, so that crucible in taking out.After the growth ending, crucible in from outer crucible, taking out is opened interior crucible, is taken out crystal ingot; And outer crucible is motionless, can repeatedly use.
Compare with the prior art of using single crucible, the present invention not only can significantly reduce the consumption of HMP crucible material, and interior crucible can not rub lagging material when taking out, thereby has prolonged the work-ing life of lagging material.In a word, apparatus of the present invention can be simplified technology, reduce cost.
