Abstract
Al2O3/ZrO2 composites have been prepared by fast firing of oxidized Al /Al2O3/ZrO2 precursors produced by the reaction-bonded aluminium oxide (RBAO) technique. This fabrication route results in high-strength cer amics at relatively low densities. For example, after fast firing for 20 min at 1550 degrees C, RBAO containing 20 vol% ZrO2 shows four-poin t bending strengths of > 600 MPa at a density of similar to 95% theore tical which is comparable to conventionally sintered RBAO.
