Abstract

Compositional design and optimization of processing parameters are key factors for controlling and improving the properties of SiC-based electroconductive ceramic composites. Temperature rising time of sheath heater is 1.1 times faster than SiC ceramic heater. Heating insulation of SiC ceramic heater is 2.7 times larger than sheath heater. If SiC ceramic heater is one body type of a product application, contact resistance will decrease. I think that temperature initial rising time is faster than now. The more SiC ceramic heater is used for a long time, the more economic benefit is larger in the view point of heat insulation.

SiC에 기초한 도전성 복합체의 최적 설계 요소와 세라믹 제조기법을 찾고 발열체 제작을 위한 기초기반 기술을 확보하였다. 제품 응용시 세라믹 발열체를 하나의 몸체로 제작하여 접촉 저항을 최대한 줄이면 sheath 발열체보다 1.1배 느린 초기 상승 온도 속도를 높일 수 있고, 보온력에서는 SiC계 세라믹 발열체가 sheath 발열체보다 약 2.7배 높기 때문에 제품의 사용 기간이 길어질수록 에너지 절감 효과를 얻을 수 있어, 경제성 면에서 대단히 유리하게 평가 된다.
