Abstract In this research, the effects of doping Lu 2 O 3 to α‐Bi 2 O 3 in the range of 0.01 < x < 0.10 in a series of different mole fractions (1% < n < 10% mole ratios) was studied. Beside, heat treatment was performed by applying a cascade temperature rise in the range of 700‐800 °C for 72 hours and new phases were obtained in the (Bi 2 O 3 ) 1‐ x (Lu 2 O 3 ) x system. After heat treatment for 72 hours at 800 °C; mixtures, containing 2‐8% mole Lu 2 O 3 , formed a tetragonal phase. As a result of subjecting mixtures, containing 9% and 10% mole Lu 2 O 3 , to a quenching process at 825 °C, tetragonal phases were obtained. With the help of XRD, the 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 β‐Bi 2 O 3 doped with Lu 2 O 3 was measured using the four‐probe DC method.
