The cold swaging over the reduction of 90% is found to be effective to improve the final relative density to that for a bulk, sintered billet and to reduce the final grain size to be half. Due to the grain size reduction and high densification, the hardness of resintered Al2O3 billet becomes equal to or larger than that of bulk, dense Al2O3.
