Silicon Carbide Heating Rods Description
Silicon carbide heating rod is a high-temperature nonmetal heating elements which are processed by silicon carbide. Comparing to other metal elements, silicon carbide heating element has many advances such as high working temperature, oxidation resistance, longer life, and corrosion resistance.
The cold ends are impregnated with silicon metal - referred to as one piece, and low resistance cold ends which are furnace welded to the hot zone - referred to as a three-piece or LRE (Low Resistance End) type. This lower electrical resistance cold end causes them to operate at a lower temperature. The extremities of the elements are metalized with aluminum to provide a low resistance contact surface to which the electrical connections are made using braided aluminum straps.
