  With the development of semiconductor, thin quartz glass has been widely used in many occasions, people with their wisdom, the product R & D out many kinds and characteristics of thin quartz glass sheet, and you know what? Below by Beijing kailiaa quartz glass instrument factory Xiaobian to introduce you.

  With the development of semiconductor technology, quartz glass is widely used in various processes of semiconductor manufacturing. For example, the direct pulling method to convert polycrystalline silicon into a single crystal; cleaning with the cleaning tank; diffusion of the diffusion tube, when the boat; ion implantation with the bell cover, and so on. Silica glass is a kind of special glass containing only silica. The types, preparation technology, raw materials, abroad is often called silicate glass, quartz glass, fused quartz, fused quartz, synthetic fused quartz, and the lack of a clear concept of the transparent, translucent, opaque quartz etc.. Our country referred to as quartz glass, according to the process, use and appearance to classification, such as electric melting transparent quartz glass, even fused quartz glass, gas semltime quartz glass, synthetic quartz glass, opaque quartz glass, quartz glass, semiconductor quartz glass, electric light source with a quartz glass.

  In the traditional energy is on the verge of exhaustion, oil, coal and natural gas prices soaring, the urgency of the situation, one of the new energy solar energy has attracted world attention, as solar cells the main raw material polysilicon demand quantity also in dramatic growth. In the polycrystalline silicon ingot production process, in order to prevent the molten silicon and quartz ceramic crucible reaction and easy demoulding separation and need to in the crucible coating on the surface of. Fused quartz crucible is necessary container production of solar polysilicon ingot, for convenient demoulding, on its inner surface spraying a layer of silicon nitride. The high purity silicon nitride powder spraying in domestic quartz crucible, the spraying silicon nitride slurry when quartz substrate temperature and film thickness of quartz crucible silicon nitride coating bonding strength.
