Abstract: The binary systems Bi2O3-Dy2O3 and Bi2O3-Pr2O3 have been investigated by doping Dy2O3 and Pr2O3 in the composition range 10 - 40 mole % prepared by ceramic method. From the phase evolution studies of Dy2O3 doped samples, it was observed that fluorite structured f c c phase is stabilized for the composition range 10-40 mole %. The stability of d- phase was affected by the heat treatment temperatures. The higher the content of dopant concentration, the higher was the sintering temperature. The lattice parameter for Dy2O3 doped samples decreased with the increase of dopant concentration and obeyed Vegard’s rule. From the structural studies of Pr2O3 doped samples rhombohedral phase was found for 10 to 30 mole % of dopant concentrations. For 40 mole % of dopant concentration, the impurity peaks were observed in the XRD patterns along with rhombohedral phase. The unit cell parameters for Pr2O3 doped samples were evaluated on hexagonal settings.
