Abstract: The effect of temp., V concn., and degree of acidification of the soln. on the compn. of Sr polyvanadates arising in the system Sr(VO3)2-HClO4-H2O was investigated. According to variation of these conditions, 3 types of solid substances were formed: Sr(VO3)2.4H2O, SrV6O16.nH2O [nϵ6-10], and Sr1-xH2xV6O16.nH2O [xϵ0.3-0.6, nϵ5-8]. These substances were identified by means of chem. anal., x-ray diffraction, and IR spectroscopy. The last method was also used for investigating the shifts in absorption bands of IR spectra of the deuterated solid substances.
