    Abstract: In the present invention, there is provided a method for producing a self-supporting ceramic body by the oxidation of a parent metal to form a polycrystalline ceramic material consisting essentially of the oxidation reaction product of said parent metal with an oxidant, including a vapor-phase oxidant, and optionally one or more metallic constituents. The method comprises the steps of providing at least a portion of said parent metal with a barrier means at least partially spaced from said parent metal for establishing at least one surface of the ceramic body, and heating said parent metal to a temperature above its melting point but below the melting point of the oxidation reaction product to form a body of molten metal. At that temperature, the molten metal is reacted with the oxidant, thus forming the oxidation reaction product. At least a portion of the oxidation reaction product is maintained in contact with and between the molten metal and oxidant to transport the molten metal through the oxidation reaction product toward the barrier means and into contact with the oxidant so that the oxidation reaction product continues to form at the interface between the oxidant and previously formed oxidation reaction product optionally leaving metal dispersed through the polycrystalline material. The reaction is continued to the barrier means to produce a ceramic body having the surface established by the barrier means. A composite is formed by superimposing a barrier onto a filler material, such as a preform, and infiltrating the filler with the polycrystalline ceramic matrix grown to the barrier means.

    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.
