Silicon Carbide SiC Material Properties
Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. 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.
Testing Prevents Surge in Arrester Failures | T&D World
Silicon-carbide arresters are currently less popular than the metal-oxide varistor (MOV), yet a great nuer of them are still in service.
