Abstract: This invention relates to a method for producing a self-supporting ceramic structure comprising an oxidation reaction product of a parent metal and a vapor-phase oxidant characterized by a refined microstructure attributable to the addition of one or more process modifiers relative to substantially the same oxidation reaction product produced without a process modifier.

Abstract: A method for producing a self-supporting ceramic composite which comprises preparing a polycrystalline material as the oxidation reaction product of a parent metal with a vapor-phase oxidant, comminuting the resulting material to a particulate, forming a permeable mass of said particulate as filler, and infiltrating said particulate with an oxidation reaction product of a parent metal with a vapor-phase oxidant, thereby forming said ceramic composite.

Abstract: A method is provided for producing a self-supporting ceramic composite body having a plurality of spaced apart wall members, each wall member having a bounded cross-­section for defining substantially continuous, fluid passageways. The wall members generally inversely replicate in opposed directios the geometry of a positive pattern. Each of the wall members, which are axially aligned, comprises a ceramic matrix having a filler embedded therein, and is obtained by the oxidation reaction of a parent metal to form a polycrystalline material which consists essentially of the oxidation reaction product of the parent metal with an oxidant and, optionally, one or more metals, e.g. nonoxidized constituents of the parent 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.
