Phase equilibria in the Tl2MoO4–R2(MoO4)3–Zr(MoO4)2 (R = Al, Cr) systems: synthesis, structure and properties of new triple molybdates Tl5RZr(MoO4)6 and TlRZr0.5(MoO4)3

Abstract


The Tl2MoO4–R2(MoO4)3–Zr(MoO4)2 (R = Al, Cr) systems were studied in the subsolidus region using X-ray powder diffraction and differential scanning calorimetric (DSC) analysis. Quasi-binary joins were revealed, and triangulation was carried out. New ternary molybdates: Tl5RZr(MoO4)6 (5:1:2) and TlRZr0.5(MoO4)3 (1:1:1) (R = Al, Cr) were prepared. The unit cell parameters for the new compounds were calculated.
