Synthesis of double molybdate-phosphates of Pr(Eu)2+1/3xZr3(MoO4)9-x(PO4)x composition

There had been obtained complex molybdate-phosphates of Ln2+1/3xZr3(MoO4)9-x(PO4)x composition, where Ln = Pr, Eu, x = 0.1-0.8, synthesized by the method of solid-phase reactions. The possibility of solid-phase synthesis of new molybdate-phosphates by substitution of (МоО4)2- to (РО4)3- in double zirconium-containing molybdates was studied and the influence of chemical composition on stability of crystal structure had been determined.
