Non-oxide Ceramics – Silicon Carbide (SiSiC/SSiC)
Worth knowing: Properties of Silicon Carbide (SSiC / SiSiC) Low density (3.07 to 3.15 g/cm 3) High hardness (HV10 ≥ 22 GPa) High Young’s modulus (380 to 430 MPa) High thermal conductivity (120 to 200 W/mK) Low coefficient of linear expansion (3.6 to 4.1x10-6 /K at 20 to 400 C)
This coating is used to infiltrate and seal porous graphite, carbon fiber composites, and similar porous substrates used in harsh environments. GraphiSeal has even been used to seal porous ceramics. For additional enhanced properties GraphiSeal can be coined with particulate fillers such as alumina, silicon, SiC, and other fillers to modify both internal and coated surface properties.
