Abstract

The invention provides a carbon paper laminated composite thermal insulating lining of a Czochralski silicon furnace. The carbon paper laminated composite thermal insulating lining comprises a substrate formed by curling flexible graphite paper, wherein an adhesive is applied between the curled contact surfaces of the substrate to form an adhesive layer. Consequently, a composite thermal insulating material composed of the flexible graphite paper and the adhesive material is formed. The carbon paper laminated composite thermal insulating lining provided by the invention is small in thermal conductivity coefficient, good in thermal barrier effect, high in temperature rise and fall rate, and low in thermal inertia. Furthermore, the carbon paper laminated composite thermal insulating lining is stable in thermal field system and excellent in thermal insulation properties. Besides, the carbon paper laminated composite thermal insulating lining is convenient to operate and advantageous for 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...
