Silicon Carbide (SIC)
Silicon carbide (SiC) is an ultra-hard ceramic material, with a hardness second only to diamond. It offers exceptional wear resistance, high strength, and outstanding thermal and chemical stability, making it ideal for extreme environments. SiC ceramics maintain their mechanical properties even at high temperatures, with excellent resistance to corrosion, oxidation, and thermal shock.
Mascera provides two types of SiC ceramics: sintered silicon carbide (SSiC), known for its high purity, superior hardness, and extreme wear resistance, and reaction bonded silicon carbide (RBSiC/SiSiC), which offers good thermal shock resistance and structural strength. These materials are widely used in mechanical seals, valve components, bearings, semiconductor processing, and high-temperature industrial applications.
