　　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℃, Its resistance rate is 600~1400Ωm㎡/m .Tts resistance value changes along with the temperature rising. From room-temperature to 800℃ is negative value,over 800℃ is positive value nature curve.
