Abstract
The effect of MgO and ZrO2 dopants, added separeately or simultaneously, on the grain size, denisity, and toughness of Al2O3 was studied. Small ZrO2 addotoopms (<100 ppm) had little effect, whereas larger amounts decreased the sintered density. Additions of Mgo Up to the solubility limit (∼ 300 ppm) increased both density and grain size; further additions had little effect on the density but strongly reduced grain size.Keywords
