Abstract
Silicon-carbide-whisker-reinforced cordierite ceramic products are prepared by uniformly incorporating the whiskers in the ceramic batch, forming the batch into a product preform, e.g. by extrusion, and firing the preform according to a process wherein the conversion of the oxide batch materials to cordierite occurs under a non-oxidizing atmosphere. Significant improvements in product strength and thermal downshock resistance are obtained.
