Abstract : Stabilized zirconia containing sintered particles of alumina and zirconia in tetragonal phase is prepared by mixing alumina particles of less than 30 nanometers with zirconia particles of less than 30 nanometers in, presence of a liquid to form a suspension, drying the suspension at a temperature up to about 600 deg C to remove the liquid and products thereof to form a dried suspension composed of agglomerated alumina and zirconia particles, sintering the dried suspension to fuse the particles and cooling the sintered dried suspension to an ambient temperature to produce free-standing bodies or coatings on substrates.
