ABSTRACT:
A process for producing a sturdy refractory metal oxide article includes the steps of heating a substrate of organic material impregnated with a metal compound to thermally decompose the compound without substantial thermal decomposition of the substrate, further heating to decompose and remove the organic material and complete conversion of the compound to a metal oxide so that a metal oxide replica of the substrate remains and further heating to sinter and densify the replica such that the replica has a strength (shock resistance) figure of merit of at least three g-meters and the replica retains such strength after heating to 1500 C.
