Abstract: There is disclosed a method for producing a self-supporting ceramic body by oxidation of a molten precursor metal with a vapor-phase oxidant to form an oxidation reaction product and inducing a molten flux comprising said molten precursor metal through said oxidation reaction product. A second metal is incorporated i said molten flux during the oxidation reaction. The resulting ceramic body includes sufficient second metal such that one or more properties of said ceramic body are at least partially affected by the presence and properties of said second metal.

Abstract: A method for producing a self-supporting ceramic composite structure comprising a ceramic matrix embedding a filler (38) includes oxidizing a parent metal to form a polycrystalline material comprising the oxidation reaction product of the parent metal with an oxidant and, optionally, one or more metallic constituents, and the filler (38) embedded by the matrix. The method includes heating the parent metal to provide a first source (36) of molten parent metal and a reservoir (34) of molten parent metal and contacting the first source (36) of molten parent metal with a permeable bedding of filler (38). The first source (36) of molten parent metal is reacted with the oxidant to form the oxidation reaction product and is replenished from the reservoir (34) as the reacting continues for a time sufficient to grow the oxidation reaction product to a desired boundary and thereby embed at least a portion of the bedding of filler (38) within the oxidation reaction product to form the ceramic composite structure. The bedding of filler (38) may have any suitable shape, including that of a hollow body, the interior of which is contacted by the first source (36) of molten parent metal to grow the oxidation reaction product through the shaped, hollow body of filler.
