Phase relations in the system SbVO5-Sb3V2Mo3O21 in solid-state and in the atmosphere of air

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 Sb_{1-6x □ x}V_{1-6x □ x}Mo_10xO₅ 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%.
