Na2MoO4-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.
