Metallic heating elements (wire wound, rod over bend) can be used up to 2400 degF (1315 degC), some SiC heating elements can be used up to 3000 degF (1650 degC) and MolyD heating elements can be used up to 3360 degF (1850 degC. Graphite heating elements (in Argon) can be used up to 3000 degC. Besides the maximum temperature, the atmosphere in the furnace is a controlling factor to select heating elements.
For electrically heated systems we use metallic, Silicon Carbide (SiC), Molybdenum Disilicide (MoSiO2 or MolyD) or graphite heating elements.
