Crystal Structure of-AgVO3and Phase Relation of AgVO3

Phase relations of AgVO3were studied by crystal structure analysis and thermal property measurement. Crystal structure of newly defined-AgVO3was determined by XRD measurements. The structure analyzed is monoclinic [C2/c(#15)] and the crystal parameters area=10.437 ?,b=9.897 ?,c=5.532 ?, and=99.69°,-AgVO3is a metastable phase which can be formed by precipitation at an ambient temperature and/or when it is quenched from its melted state. It is also formed just below the melting point instantaneously when cooled slowly and frozen quickly.-AgVO3is irreversibly transformed into-AgVO3at around 200°C. The-phase is molten at 476°C.
