Addition of 0.15-0.5 mol % acceptor oxide, AI203, to 3 mol % Y203-ZrO2 results in enhanced densification at 1350~ The enhancement is accounted for by a liquid phase sintering mechanism. While the addition of donor oxide, Ta2Os, of 0.15 2.5 mol % at 1300-1600~ results in the decrease of final density
