説明
The phase transition and the structure of a superionic conductor Ag3SBr0.5I0.5 were investigated by specific heat, X-ray diffraction and dielectric measurements. The ordered phase (γ-phase) concerning the Ag distribution was discovered below 115 K. The transition heat and the entropy change for the γ-β phase transition are 0.19 kcal/mol. and 1.6 cal/mol. deg., respectively.<BR>X-ray structure analysis showed that the structure of the β-phase was isomorphous with that of β-Ag3SI and β-Ag3SBr, but the structure of the γ-phase was neither the same as γ-Ag3SI nor γ-Ag3SBr. The structure of γ-Ag3SBr0.5I0.5 belongs to the orthorhombic system with the lattice constant a(\simeqb\simeqc)=9.637±0.002 Å at 99 K which is almost doubled the lattice constant of the β-phase at room temperature (a=4.842±0.003 Å). The structure and the phase transitions of the system Ag3SBrxI1−x are discussed.
