Abstract: A method is disclosed for producing a ceramic body by oxidation of a parent metal, the ceramic body having a graded microstructure characterized by a plurality of zones differing from each other in one or more properties. The zones in the ceramic body are attained by altering the process conditions during formation of said ceramic body such that a zone of the oxidation reaction product formed posterior to said altering has one or more properties different from a zone of the oxidation reaction product formed anterior to said altering.
