Abstract

The invention provides a Czochralski monocrystalline silicon furnace carbon paper laminated composite thermal insulation lining, which includes a base material formed by curling flexible graphite paper, and the curled contact surfaces of the base material are coated with an adhesive to form a adhesive layer. A composite thermal insulation material composed of flexible graphite paper and bonding material is formed. The advantages of this scheme are: small thermal conductivity, good heat insulation effect, fast heating and cooling speed, and small thermal inertia. The thermal field system is stable and the thermal insulation performance is good. It is easy to operate and beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of high-temperature heat insulation materials, in particular to a carbon paper laminated composite heat insulation inner lining used in the thermal field system of a Czochralski single crystal silicon furnace. Background technique [0002] The thermal field system of the single crystal furnace is the core of the Czochralski silicon single crystal growth equipment. The quality of the thermal field has a great influence on the quality of the single crystal silicon. A suitable thermal field parameter is enough to grow high-quality single crystals, but it is not good. A certain thermal field tends to make single crystal become polycrystalline, or it is impossible to seed the crystal at all. Although some thermal fields can grow single crystals, the quality is poor, and there are dislocations and other structural defects. Therefore, to find a good thermal field condition, Configuring the best thermal field system...
