Abstract: A method of producing self-supporting ceramic structures includes providing a first self-supporting ceramic body (10) comprising (i) a polycrystalline oxidation reaction product (12) formed upon oxidation of a first molten parent metal with a first oxidant, and (ii) interconnected porosity (13) at least partially accessible from one or more surfaces (15) of said first ceramic body (10). A second ceramic body is used to form, by reaction with a vapor-phase oxidant, a second polycrystalline material which is infiltrated into the porosity of at least a zone of said first ceramic body (10).
