Abstract
It has been established by XRD, DTA and TG methods that phases of solid solution type of MoO3 in SbVO5 are formed in the system V2O5-MoO3-a-Sb2O4. The Mo6+ ions are incorporated into the crystal lattice of SbVO5 instead of both Sb5+ and V5+, while the charge compensation occurs by a formation of cation defects (□) at Sb5+ and V5+. The phases Sb1-6x □ xV1-6x □ xMo10xO5 are stable in the solid-state up to 690±10°C and the limit of solubility of MoO3 in SbVO5 does not exceed 20.00 mol%.
