【 摘 要 】

We have investigated Bi₂O₃â€�?�Eu₂O₃ binary system by doping with Eu₂O₃ in the composition range from 1 to 10 mole% via solid state reactions and succeeded to stabilize ð›�?-Bi₂O₃ phase which is metastable when pure. Stability of ð›�?-Bi₂O₃ polymorph was influenced by heat treatment temperature. Tetragonal type solid solution was obtained in 3â€�??6 mole% addition range when annealed at 750°C and the range was 2â€�??7 mole% when annealed at 800°C. We have also carried out investigations on lattice parameters, microstructural properties and elemental compositions of this ð›�? type solid solution for each doping ratio. Lattice parameters increased with amount of Eu₂O₃ addition. Our experimental observations strongly suggested that oxygen deficiency type non-stoichiometry is present in doped ð›�? type solid solutions.
