MODIFIED CERAMIC STRUCTURES AND METHODS OF MAKING THE SAME

摘要

A method of producing self-supporting ceramic or ceramic composite structures comprising (i) a polycrystalline oxidation reaction product formed upon oxidation of a body of molten parent metal with an oxidant, and (ii) interconnected porosity at least partially accessible from one or more surfaces of said ceramic or ceramic composite body. A second polycrystalline ceramic material is incorporated into the porosity of said ceramic body to modify or contribute to its properties.
