Abstract
Phase equilibria in the NaVO3–Na2WO4 two-component system and in the NaCl–NaVO3–Na2EO4 (E = Mo or W) three-component system were studied. The phase assemblages of the NaCl–NaVO3–Na2EO4 (E = Mo or W) three-component systems were analyzed. Differential thermal analysis (DTA) showed that the binary system is a eutectic system and the three-component systems are partitioned by the compound Na3ClEO4 into two secondary triangles, in each of which eutectics were found. The percentages of the components in the ternary eutectics and their melting points were determined. Phase equilibria were described for all elements of the phase diagrams studied in this work. The Na2WO4 crystallization field is represented by α, β, and γ phases, and the Na2MoO4 crystallization field, by δ, γ, and β phases. The smallest crystallization field in the ternary systems belongs to low-melting NaVO3.
