ABSTRACT:
A reactant fugitive filler material is employed in a material composition which includes alumina-based ceramics of one or more particle sizes. The reactant fugitive material provides sufficient reactant material at an elevated temperature to form a fired ceramic article which has a porous microstructure in which the grain morphology is characteristic of grains which have undergone vapor phase transport action.
