ABSTRACT Crystal structure and temperature depence ofSm2O3- Dy2O3 and Tm2O3- Dy2O3 dopedbismuth trioxide (Bi2O3) tenary solid solutions have been investigated. The (Bi2O3)1-x-y(Dy2O3)x(Sm2O3)y and (Bi2O3)1-x-y(Dy2O3)x(Tm2O3)y ternary systems were obtained with x=20,10 mol % and y=20,10 mol % dopant concentrations. The temperature dependence of the electrical properties of -phase of solid solution samples were measured by d.c. four point probe technique.The crystallographic structure of the samples were characterized by X-ray powder diffractions (XRD). The unit cell parameters were determined from the powder diffraction patterns.Thermal behavior and stability of the phases were investigated by Differential Thermal Analysis-Thermo Gravity (DTA-TG).
