Silicon Carbide Ceramic

Silicon carbide (Sic) is a micro-hole structure, in the same unit area can be more than 30% of the porosity, greatly increasing the contact with the air cooling area, enhance its cooling effect.
This series ceramics have been widely used in petroleum, chemical, automotive, mechanical and aerospace industries because of their excellent resistance to thermal shock, high temperatures, oxidation and chemical corrosion.It can also shield electromagnetic interference in electronic products.
