U-shaped Alpha Sic Rods By Silcarb Recrystallized (P) Ltd.

We are offering our customers U-Shaped Alpha SiC Rods which are manufactured by carefully matching two Alpha Rod Heating Elements and welding a thickened bridge. These are useful for elements, which required single end termination.

Electrical Characteristics of U-Shaped Alpha SiC Rods:-
The resistance of Spiroheat / Alpha Rod Element varies with temperature as detailed in the figure below. From a relatively high value at room temperature it falls to a minimum at about 800 Degree C and then gradually rises up to its maximum operating temperature. The resistance value at 1400 Degree C will approximately by 10% more than its value at 800 Degree C. The Voltage across the element and the current passing through it should be measured at about 8000C to determine the resistance (V=IR).

Element Loading
The Operating temperature of the elements is dependent on both the furnace temperature and the specific element loading, normally expressed in watts per square centimeter of the Hot Zone area.
