SiC foam ceramics was prepared via a controlled template liquid silicon infiltration process. In situ synthesis technique was used in order to grow zeolite crystals onto the substrate. The final Silicalite-1/SiC foam ceramic composite possesses multimodal (micro-/macro-) porosity, unique architecture, high surface area and outstanding interfacial bonding properties. Such materials are expected to find application in catalytic and sorption/separation fields.
