【 摘 要 】

In this study, after doping Yb₂O₃ substance to ð›�?-Bi₂O₃ substance in the range of 1% â‰�? ð‘�?? â‰�? 8% in a series of different mole ratios, heat treatment was performed by applying a cascade temperature rise in the range of 700â€�??790 °C for 48 and 120 h and new phases were obtained in the (Bi₂O₃)_{1−ð�?��?} (Yb₂O₃)_ð‘�? system. After 48 h of heat treatment at 750 °C and 120 h of heat treatment at 790 °C, mixtures containing 1â€�??8% mole Yb₂O₃ formed a tetragonal phase. With the help of XRD, crystal systems and lattice parameters of the solid solutions were obtained and their characterization was carried out. Thermal measurements were made by using a simultaneous DTA/TG system. The total conductivity (𝜎_T) in the ð›�?-Bi₂O₃ doped with Yb₂O₃ system was measured using four-probe d.c. method.
