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.
