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.
The requirements on graphite
1, High purity
2, Fine grain, uniform material structure
3, High mechanical strength
4, Thermal shock resistance
5, Suitable resistance
6, Corrosion resistance
7, Excellent thermal insulation
