Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.

Brevier Technical Ceramics - Keramverband

Boron carbide ceramics (B4C) are manufactured, similarly to silicon carbide ceramics, from sub-micron B4C powder in an inert gas atmosphere at temperatures above 2,000 C without pressure (SBC), hot Boron carbide ceramics are distinguished by their outstanding hardness, only exceeded by cubic boron nitrides and diamond.
