Material Notes:
Rocar® is an extremely lightweight silicon carbide ceramic. It permits a reduction in mass forces at high speeds, and is considered for its hardness, excellent resistance to corrosion and sudden changes in temperature, excellent anti-friction properties, and higher heat conductivity over steel. The various types of Rocar include sintered and silicon infiltrated silicon carbide. In SiSiC, the pore cavities are filled with metallic silicon. Since shrinkage during firing is minimal, complex components can be produced with low tolerances. It maximum application temperature is 1350°C. However, it is not suitable for use in highly alkaline media because of its content of metallic silicon.
