Formation of vanadium antimonate and low temperature stabilisation of β-Sb2O4by vanadium

Abstract

The formation of hitherto disputed monophasic vanadium antimonate is reported and its thermally induced decomposition into β-Sb₂ O₄ containing ca. 5% vanadium is associated with a new low-temperature stabilisation of this phase; on further heating the hexagonal ‘β-Sb₂O₄’ plate-type crystals develop crystalline outgrowths of vanadium antimonate.
