摘要：A method of making self-supporting ceramic composite structures having fillerembedded therein includes infiltrating a permeable mass of filler with polycrystallinematerial comprising an oxidation reaction product obtained by oxidation of a parentmetal such as aluminum and optionally containing therein non-oxidized constituents ofthe parent metal. The structure is formed by placing a parent metal adjacent to apermeable filler and heating the assembly to melt the parent metal and provide amolten body of parent metal which is contacted with a suitable vapor- phase oxidant.Within a certain temperature region and optionally aided by one or more dopants in oron the parent metal, molten parent metal will migrate through previously formedoxidation reaction product into contact with the oxidant, causing the oxidation reactionproduct to grow so as to embed the adjacent filler and provide the composite structure.
