Silicon Carbide (SiC) is a near-diamond-hard technical ceramic used across furnace, burner and chemical-process environments where metal parts cannot survive the heat or corrosion. RKIC supplies SiC tubes manufactured in Reaction-Bonded (SiSiC), Sintered (SSiC) and Nitride-Bonded (NSiC) grades — rated from 1380°C up to 1800°C depending on grade — as radiant burner tubes, kiln rollers, thermocouple protection sleeves, blast nozzles and wear liners, manufactured to custom shape and dimension.
