In this study, after doping Yb2O3 substance to α -Bi2O3 substance in the range of 1% ≤ n ≤ 8% in a series of different mole ratios, heat treatment was performed by applying a cascade temperature rise in the range of 700–790 °C for 48 and 120 h and new phases were obtained in the (Bi2O3)1 − x(Yb2O3)x system. After 48 h of heat treatment at 750 °C and 120 h of heat treatment at 790 °C, mixtures...
