Carbon/ceramic thermal field products are characterized by low cost, corrosion resistance and long life. They are mainly used in the melting and purification of materials (such as monocrystalline silicon or polycrystalline silicon). Among them, carbon/ceramic crucible for moncrystalline silicon pull-out furnace has produced more than 600 products of different specifications (20, 22, 24 inches), which ensures the stability of product batches, and its service life is about 30% higher than that of traditional carbon/carbon crucible. Carbon/ceramic and silicon carbide coating processing of graphite products have characteristics of high temperature resistant, light weight, high strength, can withstand 2000 ℃ high temperature. The graphite products coated with silicon carbide are resistant to high temperature, chemical corrosion and small amount of waste gas and dust. Supercode provides carbon/ceramic products and silicon carbide coating research and development, design and manufacturing, can be used in monocrystalline silicon drawing furnace, silicon epitaxial equipment, MOCVD equipment. Products include: crucible for monocrystalline silicon straight-draw furnace, outer tank of thermal screen, cauldron, cover plate, etc., graphite base of silicon carbide coating for LED epitaxy, carbon/ceramic crucible for nonferrous metal smelting, silicon carbide coating graphite plate for electronic packaging, etc.
