Silicon Carbide - AEP

Silicon Carbide Varistors are voltage dependent resistors with symmetric voltage/current characteristics and are therefore suitable for use with direct and alternating current. In case of voltage increase, the resistance value of these voltage dependent resistors gets inertia-free and exponentially lower, i.e. a slight increase in voltage effects a much higher increase in current.

New varistor material: Journal of Applied Physics: Vol 64, …

A composite varistor material containing silicon carbide, a conductor, and an insulator has been developed. The material has rubberlike flexibility and is easily formed. A higher leakage resistivity (∼10 1 2 Ω cm) and greater nonlinearity (∼10) than for silicon carbide varistors permit the material to be used as a gapless surge suppressor.

Silicon Carbide | Washington Mills

Silicon carbide (commonly referred to by its chemical formulation of SiC) is a chemical compound comprised of silicon and carbon that results in extremely hard (9 on the Mohs scale) iridescent crystals. CARBOREX ® grains and powders offer superior properties such as low density, low thermal expansion, oxidation resistance, excellent chemical resistance, high thermal shock resistance, high
