graphite thermal field for CZ single crystal
Graphite parts which are used in Cz silicon crystal growing furnace are consumable parts. They are made of a variety of high-purity, isostatic graphite. For example,graphite crucible and other parts use graphite with high purity and fine grain. Graphite heater is made of high-purity, isostatic graphite. Graphite thermal insulation cover and cover board are made of high purity,medium grain graphite.
Products: thermal insulation barrel, heater, three-segment crucible,crucible tray, draft tube, graphite electrode, electrode nut, graphite pad for cutting silicon rods, heat shield, graphite boat, etc.
