High-pressure investigations of ABiO3, A = Y3 + and Yb3 + type ternary oxides in Bi2O3-A2O3 system
In situ powder synchrotron X-ray diffraction measurements were conducted on YBiO3 and YbBiO3 under high-pressures up to approximately 20 GPa at room temperature. Although the compounds have similar compositions they crystallize in different structures, viz. YBiO3, has cubic fluorite-type lattice rel...

| description | In situ powder synchrotron X-ray diffraction measurements were conducted on YBiO3 and YbBiO3 under high-pressures up to approximately 20 GPa at room temperature. Although the compounds have similar compositions they crystallize in different structures, viz. YBiO3, has cubic fluorite-type lattice related to δ-Bi2O3 while YbBiO3 has triclinic lattice but closely related to the former. Both compounds were found to exhibit pressure-induced amorphization around 16 GPa, consistent with the behavior observed in other bismuth-based oxides. The evolution of lattice parameters and volume under pressure was determined for both YBiO3 and YbBiO3, and the obtained bulk moduli were: 59(3) and 181–254 GPa, respectively. The bulk modulus of YbBiO3 was also found to be dependent on the sample loading and compression method which can affect the inherent distortion of the lattice. Additionally, the estimated bulk modulus is discussed by highlighting the influence of the lone pair of electrons in Bi3+ ions. These findings are discussed in the context of other bismuth-based compounds and the role of the lone pair of electrons, relevant to their applications as optical and photocatalytic materials. |
