초록

탄화규소(SiC)는 기계적/화학적 특성이 우수한 소재로 항공우주, 방산, 원자력 발전과 같은 핵심 산업에서 널리 응용되고 있는 소재이다. 이러한 탄화규소는 마이크로파를 조사하면 급속발열 하는 특성이 알려져 고효율 발열체로 연구되고 있다. 본 연구에서는 폴리카보실란(Polycarbosilane)을 기계 화학적 반응법으로 아이오딘 불융화(curing)처리 하였고, 이를 열분해(Pyrolysis)하여 마이크로파 발열 소재를 제조하였다. 열분해 온도 및 아이오딘 첨가량이 마이크로파 발열에 미치는 영향을 조사하였다. 그 결과 제조된 시편은 약 60초내에 최대 800℃까지 급속 발열하는 것으로 나타났으며, 평균 700~750℃의 온도 구간에서 120분의 장시간 동안 일정하게 온도를 유지하였다.

Silicon carbide (SiC), known for its excellent mechanical and chemical properties, is widely used in key industries such as aerospace, defense, and nuclear power generation. Due to its rapid heating characteristics when exposed to microwaves, SiC is being researched as a highly efficient heating element. In this study, Polycarbosilane (PCS) was treated by a mechanochemical reaction with iodine, followed by pyrolysis to create a microwave heating material. The effects of pyrolysis temperature and iodine additive content on microwave heating performance were investigated. The results showed that the fabricated specimen rapidly heated to a maximum of 800℃ within approximately 60 sec and maintained a stable temperature of 700~750℃ for up to 120 min.
