Abstract
The utility model discloses the long brilliant stove ventilation device of a kind of modified version sapphire, belong to melt seed crystal method single crystal growth apparatus technical field.Mainly include feed channel, seed crystal supporting rod and seed chuck, air intake position, it is characterized in that: gas feeding pipe is coaxial with seed crystal supporting rod, pipeline passes bell, pipeline bottom and crucible cover upper surface flush, and air intake position is in pipeline bottom.The utility model can maintain normal thermograde in crucible effectively, keeps seed crystal face clean, and crystallization is successfully carried out, and guarantees the quality of crystal.
Description
Technical field
The utility model relates to melt seed crystal method single crystal growth apparatus technical field, relates in particular to the long brilliant stove of a kind of sapphire.
Background technology
Current sapphire both domestic and external is grown the general ventilation device of brilliant stove, and gas feeding pipe is connected with bell, and certain distance, below bell, is stamped with crucible in air intake position, and gas does not enter in crucible.Such method has following problem: gas can not enter in crucible, very little on the thermal field impact in crucible, the heat energy discharging during the interior melt crystallization of crucible can not be led away, gathering of heat energy can destroy the required normal temps gradient of crystallization, even can form thermal field thermograde reversion and can not normal crystallization, also can cause the crystal remelting of crystallization; The volatile matter that furnace high-temperature causes in addition can pollute seed crystal in seed crystal face deposition, makes initial crystallization contain impurity and affect crystal mass.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art; a kind of improved ventilation device is provided; gas can enter in crucible; the heat energy that crystallization is discharged can be led away swimmingly; effectively maintain normal thermograde; crystallization is successfully carried out, made seed crystal always in the protection atmosphere in rare gas element simultaneously, keep the clean of seed crystal face.
The technical solution adopted in the utility model is: the long brilliant stove ventilation device of a kind of modified version sapphire, mainly include feed channel, seed crystal supporting rod and seed chuck, air intake position, it is characterized in that: gas feeding pipe is coaxial with seed crystal supporting rod, pipeline is through bell, pipeline bottom and crucible cover upper surface flush, air intake position is in pipeline bottom.
As optimal technical scheme of the present utility model, described gas feeding pipe material therefor is resistant to elevated temperatures tungsten or molybdenum; Described seed crystal supporting rod material therefor is corrosion resistant stainless steel, and described seed chuck material therefor is resistant to elevated temperatures tungsten or molybdenum.
As optimal technical scheme of the present utility model, described seed chuck is spirane structure, and below making, the position height of the seed crystal of clamping is adjustable.
Compared with prior art, the utlity model has following advantage: gas feeding pipe bottom and crucible cover upper surface flush, air intake position is in pipeline bottom, and gas enters in crucible, and gas surrounds seed crystal; The body of ventilating is rare gas element, and rare gas element has larger specific heat, can absorb more heat energy, the heat energy that crucible intercrystalline discharges can be led away swimmingly by gas, thereby effectively maintains normal thermograde, avoids thermograde reversion, avoid crystal remelting, crystallization is successfully carried out; And because inert protective gas surrounds seed crystal, avoided seed crystal contaminated, it is clean that seed crystal face keeps, and guarantees the quality of crystal.
Accompanying drawing explanation
Accompanying drawing is the structural representation of a kind of embodiment of the present utility model.
Description of reference numerals: 1, crucible, 2, crucible cover, 3, gas feeding pipe, 4, seed crystal supporting rod, 5, seed crystal, 6, air intake, 7, crystal, 8, melt.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to accompanying drawing, gas feeding pipe 3 is coaxial with seed crystal supporting rod 4, the bottom of gas feeding pipe 3 is air intakes 6, seed crystal supporting rod 4 bottom clampings have seed crystal 5, gas enters in crucible 1, the heat energy discharging in the time of can absorbing crystal 7 crystallization, and heat energy is pulled away with gas, can keep crystal 7 and melt 8 normal temps gradient around, crystallization is successfully carried out.Inert protective gas surrounds seed crystal 5 around simultaneously, can keep the clean of seed crystal 5 surfaces, guarantees the quality of crystal 7.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for a person skilled in the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
