Influence of the structure of divalent metals molybdates on the phase formation in systems Na2MoO4-aMoO4-Zr(MoO4)2 (a = Mg, Mn, Zn, Са)

Department of Inorganic and Organic ChemistryNa2MoO4-AMoO4-Zr(MoO4)2 systems (A=Mn, Zn) were studied by X-ray analysis in the subsolidus range. Phase equilibria in the subsolidus range of the systems were studied by the method of “intersecting sections” taking into account the literature data on double-boundary systems. The formation of new ternary molybdates was established for the first time: S1 (1:3:1) - Na2Mn3Zr(MoO4)6; S2 (1:2:1) - Na2Zn2Zr(MoO4)5. Their subsolidus phase diagrams are given. In the triple salt system Na2MoO4-CaMoO4-Zr(MoO4)2, the formation of new phases was observed.
