Abstract: A method of producing self-supporting ceramic structures (12) comprising (i) a polycrystalline oxidation reaction product formed upon oxidation of a molten parent metal (14) with an oxidant, and (ii) interconnected porosity (13) at least partially accessible from one or more surfaces (15) of said ceramic body. A second polycrystalline ceramic material is incorporated into the porosity of said ceramic body to modify or contribute to its properties.

Abstract: Production of composite ceramic articles using a porous bed or preform of filler material (12) with a molten metal (11) in the presence of a vapor phase oxidant, for effecting infiltrating growth of a polycrystalline matrix of a metal-oxidant reaction product into the filler bed (12) or preform, wherein the filler material bed or preform has a first pore system of coarse interconnected pores, and a second pore system of finer interconnected pores defined by portions of the filler material which remain structurally stable in pore-defining arrangement during infiltration.
