    Abstract: A method is provided for producing a self-­supporting ceramic body comprising a polycrystalline ma­terial comprised of the oxidation reaction product of a parent metal (10) and having therein one or more channels which inversely replicate the geometry of a configured fugitive metal (6). The method includes providing an assembly of the configured fugitive metal (6) and the parent metal (10), optionally including a bed of per­meable filler (4), and heating the assembly to form a body of molten parent metal. The molten parent metal is oxidized under selected conditions to grow the polycry­stalline material to engulf the configured fugitive me­tal (6) (and to infiltrate the filler (4), if the filler (4) is present) and to cause the fugitive metal (6) to disperse into the engulfing polycrystalline material thereby leaving behind as the one or more channels the space formerly occupied by the configured fugitive me­tal (6). The method provides self-supporting ceramic bodies having therein one or more channels inversely replicating the shape of the configured fugitive metal (6).

    Abstract: Self-supporting bodies are produced by reactive infiltration of a parent metal (10) into boron carbide (12) typically resulting in a composite comprising a boron-containing compound and metal. The mass to be in­filtrated may contain one or more inert fillers (14) admixed with the boron carbide (12) to produce a compo­site by reactive infiltration, which composite comprises a matrix of metal and boron-containing compound embedding the filler (14). The relative amounts of reactants and process conditions may be altered or con­trolled to yield a body containing varying volume percents of ceramic, metal and/or porosity.
