Electric property of sic heating element
sic heating elementshave rather large specific resistance.When it is heated in air and the surface temperature of the hot zone reaches 1050°C,it's resistance rate is 600-1400mm2/mm and its resistance value changes as the temperature rises which is negative value from room-temperature to 800 °C and is postive value nature over 800 °C .
