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.
