| Abstract | Phase equilibria in the system ZrO2-InO1.5 have been investigated in the temperature range from 800[deg] to 1700[deg]C. Up to 4 mol%, InO1.5 is soluble in t-ZrO2 at 1500[deg]C. The martensitic transformation temperature m [lsbr;]Arrow Right[rsbr;] t of ZrO2 containing InO1.5 is compared with that of ZrO2 solid solutions with various other trivalent ions with different ionic radii. The diffusionless c [lsbr;]Arrow Right[rsbr;] t prime phase transformation is discussed. Extended solid solubility from 12.4 +/- 0.8 to 56.5 +/- 3 mol% InO1.5 is found at 1700[deg]C in the cubic ZrO2 phase. The eutectoid composition and temperature for the decomposition of c-ZrO2 solid solution into t-ZrO2 + InO1.5 solid solutions were determined. A maximum of about 1 mol% ZrO2 is soluble in bcc InO1.5 phase. Metastable supersaturation of ZrO2 in bcc InO1.5 and conditions for phase separation are discussed.
