Abstract: The composition of products formed in the La(VO₃)3-HNO₃-H₂O and Y(VO₃)₃-HNO₃-H₂O systems was studied. The polyvanadates of the composition La(HV₆O₁₆)₃.xH₂O (x = 19-21), La₂(V₆O₁₆)₃.xH₂O (x = 24-25), and Y(HV₆O₁₆)₃.xH₂O (x = 23-25) were separated and the optimum conditions of their preparation were found.
