Precursor-derived silicon carbide (SiC) ceramics have been widely used as absorbing materials, but the residual carbon sink produced by ceramicization limits their application under high-temperature and oxygen-containing conditions, such nozzle or jet vane of high-speed aircraft. In this paper, a novel molybdenum carbide/silicon (Mo2C/SiC) microwave-absorbing ceramic with two-dimensional sheet structure was obtained through pyrolysis polycarbosilane-coated sulfide (PCS@MoS2). The results indicate that addition an appropriate amount MoS2 can react free generated during PCS, thereby reducing material’s content forming Mo2C. Concurrently, layered structural characteristics are utilized to create composite within material, which enhances absorption vastly. as-prepared Mo2C/SiC sintered at 1300 °C exhibit minimum reflection loss (RLmin) −46.49 dB 8.96 GHz thickness 2.6 mm. Additionally, effective bandwidth (EAB) spans entire X-band (8–12 GHz) due combined effect multiple mechanisms.
