General Description SER

Made of special high-density reaction-bonded silicon carbide, the SER Starbar is a tube with both electrical connections on one end. The hot zone is formed by cutting a double spiral slot which reduces the cross sectional area through which current flows, resulting in higher resistance than the cold end. The cold end is formed by cutting two longitudinal slots along the length of the tube. The SER element is supplied with a ceramic collar cemented to the extremities of the cold end. The cold end of the SER element is flame sprayed with aluminum for a distance of about two inches. Flat braided-aluminum straps are held in compression with stainless steel clamps to this metallized area. The clamp is electrically insulated from the flat braid with high temperature insulation. The aluminum braid is 10 inches (254 millimeters) long and holes are provided for easy connection to the power supply.

Starbar heating elements are frequently used in the following industries:

• Glass - holding, refining and experimental glass melting
• Ceramics - firing of ferrites, steatites, titanates, tiles, refractories, dinnerware, electrical porcelain, calcining, ores, and powders
• Semi Conductor -- Diffusion and LPCVD furnaces for silicon wafers
• Metallurgical - heat treating, forging, annealing, hardening and deoxidizing, brazing, sintering powdered metal parts, and melting.
• Diecasting
• Solar Energy
• Laboratory, Research and Development
• Heating industries with application temperatures over 540ºC (1000ºF)
