Abstract

The reactivity of SbVO5, a compound known since a short time, with T-Nb2O5 in solid state in air has been investigated over the whole component concentration range of a system built by these two reacting substances. The investigation results have shown that an equimolar mixture of SbVO5 and T-Nb2O5 reacts with a subsequent formation of a hitherto unknown compound of the formula Nb2VSbO10. This compound has been characterized by the methods XRD, DTA/TG, and SEM. Its orthorhombic unit cell parameters have been calculated, and its stability in air up to 880 ± 10 °C has been proved. At this temperature, the compound melts incongruently with an accompanying deposition of solid Nb9VO25, i.e., of a compound that crystallizes in the binary oxide system V2O5–Nb2O5.
