Abstract

Reticulated porous silicon carbide ceramics (SiC RPCs) were fabricated by polymeric sponge replication using preset roller method, then recoating by centrifuging technique. Preparation and properties of the SiC RPCs prepared by roller method are presented in this communication. The loading content and pore diameter of the RPCs body greatly depends on the slurry viscosity. At the same time, the strut diameter and cell size of SiC RPCs are modulated by the recoating slurry.
