Device capable of reducing adhesion of volatile matters on window of reflecting screen of sapphire single crystal furnace

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 [0001] The invention relates to a device capable of reducing the adhesion of volatile matter on the viewing window of a sapphire single crystal furnace reflection screen. Background technique [0002] Sapphire has become a hot spot in research and development and industrialization in the world in recent years. During the growth process of sapphire, a large amount of metal volatiles will be generated in the single crystal furnace. The volatiles are easy to adhere to the window of the reflective screen on the sapphire single crystal furnace. It is difficult to remove and accumulate over time. It will gradually narrow the viewing window, resulting in a reduction in the observation range in the furnace. Therefore, how to reduce the adhesion of volatiles, reduce the difficulty of cleaning volatiles, and ensure that the growth of sapphire single crystal in the furnace can be better observed during the seeding process has become an urgent problem for producers to so...
