The graphite three-lobed pot has good thermal conductivity and high temperature resistance. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance to rapid heating and cooling.

Changrui graphite has been continuously improving the production process, and graphite products-graphite heaters and other products have become popular products at present.

Graphite insulation tube is mainly used in graphite crystal thermal field system of single crystal furnace.
