Abstract: | We have investigated Bi2O3-Eu2O3 binary system by doping with Eu2O3 in the composition range from 1 to 10 mole% via solid state reactions and succeeded to stabilize β-Bi2O3 phase which is metastable when pure. Stability of β-Bi2O3 polymorph was influenced by heat treatment temperature. Tetragonal type solid solution was obtained in 3–6 mole% addition
range when annealed at 750°C and the range was 2–7 mole% when annealed at 800°C. We have also carried out investigations on
lattice parameters, microstructural properties and elemental compositions of this β 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
β type solid solutions. |
