ABSTRACT:
An alumina based ceramic composition is provided containing (in volume percent, v/o): about 1.5 to 37.5 whiskers; about 5 to 17.5 zirconia; residue of a magnesium oxide addition added in an amount of about 0.03 to 3 v/o; and an alumina based matrix in which the silicon carbide whiskers, zirconia and residue of magnesium oxide are substantially homogeneously distributed. At least 2 v/o of the alumina based ceramic composition is tetragonal zirconia.
