1, Czochra monocrystalline silicon thermal field and polycrystalline silicon ingot furnace heater:
In the thermal field of czochralcian monocrystalline silicon, there are about 30 kinds of isostatic pressed graphite components, such as crucible, heater, electrode, heat shield plate, seed crystal holder, base for rotating crucible, various round plates, heat reflector plate, etc. Among them,80% of the isostatic pressed graphite is used in the manufacture of crucibles and heaters. In the manufacturing process of solar cell polycrystalline silicon wafer, the polycrystalline silicon fragments must first be fused and cast into polycrystalline silicon square ingot. The heater of the ingot furnace needs to be made of isostatic graphite.
2. Atomic Energy Industry:
In nuclear fission reactors (high temperature gas cooled reactors), graphite is a moderator of neutrons and an excellent reflector. Graphite material with good thermal conductivity and high mechanical strength is used as the first wall material facing the plasma.
3, discharge electrode:
Electric discharge machining, which mainly uses graphite or copper as electrode, is widely used in metal mold and other processing fields.
4. Graphite crystallizer for non-ferrous metal continuous casting:
Due to its good performance in heat conduction, thermal stability, self-lubrication, anti-infiltration and chemical inertiation, isostatic pressed graphite has become an irreplaceable material for making crystallizers.
