Description
Technical field
The present invention relates to sapphire crystal growing furnace ancillary equipment fields, in particular to a kind of raw for sapphire crystal
Long washes crystal structure.
Background technique
The sapphire crystal growth technique of mainstream in the world is kyropoulos, czochralski method, EFG technique and heat-exchanging method at present,
And the sapphire crystal of kyropoulos technique growth accounts for about the 70% of existing market.Low cost, in high quality growing large-size are blue precious
Stone crystal has become the urgent task currently faced.Kyropoulos are the seed crystal and melt contacts that one is cooled, if interface
Temperature is lower than freezing point, then seed crystal starts to grow.In order to make crystal constantly grow up, it is necessary to gradually decrease the temperature of melt, together
When decentralization and rotating crystal to improve the Temperature Distribution of melt, can also slowly or upper body crystal stage by stage, to expand
Big radiating surface.
During sapphire crystal growth, when due to material, it may appear that a large amount of oxide, the oxide are condensing in
Seed crystal face will have a direct impact on the growth arrangement of crystal, to directly influence the quality of entire crystal if do not removed.
So generally requiring technical staff during seeding and seed crystal being inserted into solution, and rapidly stir back and forth, wash
Remove to condense in the oxide of seed crystal face.
There are two ways to washing crystalline substance of sapphire seed crystal at present, one is seed crystal rotation is driven by rotation seed rod, separately
One is by catching the welding bellows on the outside of seed rod, the seed rod of the inside is thumped by the deformation of bellows.But
Seed rod is rotated often because not fast and seed crystal and solution enough the friction of the speed of rotation is not big enough, is not properly cleaned clean table
The oxide in face;By the bang of bellows, often because can not master the dynamics completely, so that bang dynamics is excessive, lead
Seed crystal fracture is caused, while also having directly influenced the service life of welding bellows.
Summary of the invention
It is a primary object of the present invention to overcome deficiency in the prior art, it is simple, at low cost to provide a kind of structure design
Honest and clean, can be used to remove seed crystal face oxide before automatic seeding washes crystal structure.In order to solve the above technical problems, solution of the invention
