Abstract: The influence of temperature, vanadium concentration, degree of solution acidification, and reaction time on composition of the solid polyvanadates arising from the system Mn(V0₃)₂—HNO₃—H₂0 was studied. Besides some products of varying composition, a compound of the composition Mn(HV₆0₁₆) ₂ .₁₄H₂0 was obtained from the system. It results from the study of thermal properties of this substance that the process of water liberation is of gradual character and the full dehydration is succeeded by a decomposition of original structure yielding V₂0₅ and Mn(V0₃) ₂ .
