GDU TYPE sic heating element
Electric properties of elements
SIC heating elements has rather higher specific resistance . When it is heated in air and the surface temperature of the hot zone reaches 1050 degree , its resistance rate is 600~1400 ohm mm2/m . Its resistance value changes along with the temperature rising . From changes along with the temperature rising . From room-temperature to 800 degree is negative value , over 800 degree is positive value nature curve.
