Abstract
The utility model discloses a multi-die crystal growing apparatus based on a die guide method. The multi-die crystal growing apparatus comprises a crucible, a plurality of dies, a heat insulation cover, a seed rod and a seed crystal, wherein the plurality of dies are uniformly arranged in the crucible in a star shape, the center position of the die is on the circumference taking the center of the crucible as the center of circle, the heat insulation cover is covered above the crucible and is provided with through holes which are matched with the dies from top to bottom in number and shape, the upper part of the seed rod is connected with a nut, the lower part of the seed rod is provided with producing parts with number equal to that of the dies, each protruding part is provided with a seed crystal clamping head, each seed crystal clamping head is provided with a seed crystal, the seed crystal is in a barrel shape, and each seed crystal is aligned to one die. According to the multi-die crystal growing apparatus, the plurality of dies are used for the growing of the crystal, so that the number of the crystals growing in unit time is great, the mass is great, and the multi-die crystal growing apparatus has the advantages of saving materials and being few in processing procedures.
Description
Technical field
The utility model relates to field of crystal growth, relates in particular to the device of realizing the growth of guided mode fado mould crystal.
Background technology
Artificial crystal material is in the forward position of novel material scientific development, and functional crystal material runs through many fields of hi-tech, has become the important substance basis of the developments in Hi-Tech such as microelectronics, optics, laser, remote sensing, communication, space flight, aerospace.
Along with the development of modern science and technology, modern industry is more and more large to the demand of sapphire window gate material.The sapphire single-crystal window material all is to rely on traditional complete processing all the time.Traditional complete processing obtains sapphire blank rod through round as a ball, cutting, grinding, operation is many, the time is long, effective rate of utilization is low, the work material waste is serious.And the guided mode method has the advantage of once shaped, fast growth, conservation, minimizing manufacturing procedure and becomes the method that has superiority very much of sapphire window gate material that obtains.
For guided mode method growing crystal, the number of wafers that number of molds is the more grown just the more, so the crystal mass of growth in the unit time is just larger, and the multi-mould of realizing the guided mode method is grown simultaneously and also had energy-saving and cost-reducing advantage.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of multi-mould crystal growing apparatus that grows most amount crystal within the unit time to be provided.
The utility model is achieved through the following technical solutions:
A kind of multi-mould crystal growing apparatus based on the guided mode method, include crucible, several moulds, stay-warm case, seed rod and seed crystal, described several moulds become star to be evenly arranged in the described crucible, corner dimension between each mould is 360 degree/number of molds, the central position of mould is on the circumference take the crucible center as the center of circle, described stay-warm case covers on the top of crucible, described stay-warm case has the communicating pores that is complementary with described number of molds and shape from top to bottom, lift when drawing at crystal, be used for holding crystal, the center of stay-warm case outline and star center are on same medullary ray, described seed rod top connects a nut, the quantity convex part identical with mould arranged at the bottom, each convex part is all installed a seed chuck, each seed chuck is installed a seed crystal, and described seed crystal is for directly barrel-shaped, and each seed crystal is aimed at a mould by the communicating pores on the stay-warm case.
Put 2 to 36 moulds in the described crucible; Described stay-warm case can also be columniform, and inner direction of principal axis along cylinder has cylindrical hole, and through hole and stay-warm case outline are concentric cylinder.
The utility model has the advantages that: the utility model has used a plurality of moulds to use growth with crystal, can make the amount of crystals of growing within the unit time many, and quality is large, has conservation, advantage that manufacturing procedure is few.
