Abstract
The invention discloses a device capable of reducing adhesion of volatile matters on a window of a reflecting screen of a sapphire single crystal furnace. The device is characterized by comprising a molybdenum tank body which is arranged in the window of the reflecting screen of the sapphire single crystal furnace to reduce volatile matters from adhering to the window and is detached to clean. The molybdenum tank body is provided with a high temperature resisting self-cleaning inadhesive coating layer. The device provided by the invention aims to overcome deficiencies in the prior art, and provides a device which is simple in structure and convenient to use, and is able to reduce adhesion of volatile matters on the window of the reflecting screen and reduce the cleaning degree of volatile matters, so that inconvenience for observation caused by the narrow window is avoided.
Description
Technical field
The present invention relates to a kind of device that can reduce volatile matter and adhere on sapphire single-crystal furnace radiation shield viewing window.
Background technology
Sapphire becomes world research exploitation in recent years and industrialization focus, a large amount of metal volatile matters can be produced in single crystal growing furnace in sapphire growth process, volatile matter easily on sapphire single-crystal furnace, radiation shield viewing window adheres to, not easy-clear, accumulate over a long period and viewing window can be made to narrow gradually, cause the range of observation in stove to reduce.Therefore, how to reduce the adhesion of volatile matter, reduce the difficulty of volatile matter cleaning, ensure the growing state better can observing sapphire single-crystal in stove in seeding process, become the problem that the producer solves in a hurry.
Summary of the invention
The object of the invention is to overcome weak point of the prior art, there is provided a kind of structure simple, easy to use, the adhesion of volatile matter on upper radiation shield viewing window can be reduced, reduce the cleaning difficulty of volatile matter, avoid observing the device of making troubles because viewing window narrows to crystal growth.
In order to achieve the above object, the present invention adopts following scheme:
A kind of device that can reduce volatile matter and adhere on sapphire single-crystal furnace radiation shield viewing window, it is characterized in that: include to be arranged in sapphire single-crystal furnace radiation shield viewing window and can reduce volatile matter and stick to viewing window place and the molybdenum matter cell body that cleaning can be dismantled, described molybdenum matter cell body is provided with and does not high temperature resistantly self-cleaningly cover dope layer.
The device that can reduce volatile matter and adhere on sapphire single-crystal furnace radiation shield viewing window as above, is characterized in that the shape of described molybdenum matter cell body is identical with the shape of viewing window.
The device that can reduce volatile matter and adhere on sapphire single-crystal furnace radiation shield viewing window as above, is characterized in that high temperature resistant self-cleaning not cover dope layer be that ZS-522 is high temperature resistant does not self-cleaningly cover dope layer.
In sum, beneficial effect of the present invention:
Current upper radiation shield viewing window easily adheres to a large amount of volatile matter, and is difficult to cleaning, and advantage of the present invention is on upper radiation shield, add a molybdenum matter cell body similar with viewing window shape, and coats that ZS-522 is high temperature resistant does not self-cleaningly cover coating.ZS-522 is high temperature resistant self-cleaning do not cover paint coatings surface have not easily the special functional coating that adheres to by other viscous substances or be easily removed after adhering, heatproof can up to 2000 DEG C.On the other hand, molybdenum matter cell body can be dismantled, such easy cleaning or replacing, can prevent volatile matter from directly sticking on radiation shield viewing window.Structure of the present invention is simple, easy installation and removal.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the present invention to be described further:
As shown in Figure 1, a kind of device that can reduce volatile matter and adhere on sapphire single-crystal furnace radiation shield viewing window, include to be arranged in sapphire single-crystal furnace radiation shield viewing window 1 and can reduce volatile matter and stick to viewing window 1 place and can the molybdenum matter cell body 2 of disassembly, cleaning, described molybdenum matter cell body 2 is provided with and does not high temperature resistantly self-cleaningly cover dope layer 3.
The shape of the matter of molybdenum described in the present invention cell body 2 is identical with the shape of viewing window 1.The wherein said high temperature resistant self-cleaning dope layer 3 that do not cover self-cleaningly does not cover dope layer for ZS-522 is high temperature resistant.
In the present invention when loading onto radiation shield, molybdenum sheet cell body being snapped in viewing window place, ensureing that it steadily; In temperature-rise period, because there is molybdenum matter cell body to block, volatile matter can not stick to radiation shield viewing window place, and molybdenum sheet cell body scribbles non-viscous paint, volatile matter is not easily stained with simultaneously; Taken out after growth, cleaning volatile matter.By above measure, volatile matter can be avoided to accumulate at upper radiation shield viewing window place, cause viewing window to narrow.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
