Description
Technical field
It the utility model is related to a kind of heating body structure of sapphire single-crystal furnace, and in particular to a kind of large-size sapphire list
The heating body structure of brilliant stove.
Background technology
Synthetic sapphire（Al2O3）Also known as white stone, it is transparent, it is a kind of physical characteristic, mechanical property and chemical characteristic three
The excellent material of unique combination.There is identical optical characteristics and mechanical property with natural gemstone, and have good thermal characteristics, pole
Good electrical characteristic and dielectric property, chemical property is highly stable, and most of acid solutions can not dissolve it；Translucidus can be good, it
To infrared light transmission height；Wear-resisting, hardness is only second to diamond, up to 9 grades of Mohs；Still there is preferable stability at high temperature,
The fields such as industry, national defence, Aero-Space are widely used in, are such as used as Solid State Laser, infrared window, the lining of semiconductor chip
Egative film, accurate abrasion-resistant bearing materials etc..With the continuous expansion of sapphire application field, national defence, Aero-Space, consumer electronics
Product etc. is continuously increased to sapphire demand, size, and small size sapphire single-crystal can not meet the current market demand,
Therefore, high-quality is produced, large-sized sapphire single-crystal is current top priority.
Large-size sapphire single-crystal is advantageous to improve volume recovery, reduces cost, improves production efficiency, there is economic effect well
Benefit and market prospects, it is the inevitable direction of sapphire industry development.However, as single crystal growing furnace size increases, by single crystal furnace structure
Limitation, the thermograde of traditional thermal field is small, skewness, and the difficult control of the speed of growth, growth difficulty significantly increases.Grow
Sapphire single-crystal stress it is big, easily there is the defects of viscous crucible, twin crystal, crystal growth yield rate is low.Therefore, large-size sapphire list
The design of thermal field structure in brilliant stove, especially heating body structure is most important.
The content of the invention
The utility model is directed to the subject matter occurred in the growth course of large-size sapphire single-crystal, during long crystalline substance
Occur viscous crucible, twin crystal, cloud and mist the defects of, on the basis of original heating body structure, redesigned, formed one kind be suitable to
The heating body structure of the large-size sapphire single-crystal stove of growing large-size sapphire single-crystal.
What the purpose of this utility model was realized in：It wins in succession structure, the spiral shell of side including two semicircle copper electrodes
Line jackscrew structure, staged reducing tungsten bar structure and horizontal semi-circular tungsten bar structure, semicircle copper electrode connecting plate inner ring have with
There is the screwed hole fixed with big bell electrode the through hole that tungsten bar diameter matches, outer ring；The jackscrew screw thread of electrode connecting plate side
Hole is mutually perpendicular to electrode top through hole, and wherein staged reducing tungsten bar both ends are located at logical on semicircle copper electrode connecting plate
In hole, it is fixedly connected by the screw thread jackscrew structure of side, is integrally arranged into birdcage shaped configuration；Laterally semicircle tungsten bar is distributed in
Inside and outside birdcage shaped configuration, tightened with longitudinal tungsten bar junction by tungsten filament.
The utility model also has so some features：
1st, described semicircle copper electrode connecting plate interior diameter is 450 ~ 700mm of Φ, and thickness is 30 ~ 60mm, inner ring has 40 ~
80 with the manhole of tungsten bar diameter matches, there are 5 ~ 12 screwed holes being fixedly connected with big bell copper electrode, side in outer ring
Jackscrew screwed hole totally 30 ~ 60, a diameter of 0.3 ~ 1mm of Φ.
2nd, the calandria of described birdcage shaped configuration is formed by the tungsten bar bending of the thin staged increase of the thick mid diameter in both ends.
2 ~ 10mm of tungsten bar diameter of phi.
3rd, the horizontal semicircle a diameter of 2 ~ 8mm of Φ of tungsten bar, are arranged in inside and outside birdcage shaped configuration respectively.
The utility model beneficial effect has：
1. tungsten bar staged variable diameter design can increase in-furnace temperature gradient, thermal field is set evenly to be advantageous to crystal growth
The control of speed, reduce the internal stress of crystal.
2. bulk temperature gradient increases, the speed of growth is uniform, is advantageous to growing large-size sapphire single-crystal, avoid viscous crucible,
The crystal defects such as cloud and mist, fault, improve crystal growth yield rate.
3. carrying out chamfering in the change path position of calandria, concentrated stress at reducing is avoided, what calandria was not easily broken asks
Topic, increases the service life.
