Abstract
The aim of this work is to investigate the double salt systems of Tl2MoO4-Ag2MoO4 and Tl2WO4-Ag2WO4using the method of X-ray phase analysis. The formation of a limited number of solid solutions in these systems is shown. In the sub-solidus region of the thallium silver containing molybdate system, the formation of a limited solid solution has been revealed, resulting from a high-temperature modification of thallium molybdate with an extension of up to 73 mol. %. At the same time, a solid solution in the thallium-containing tungstate system on the side of thallium tungstate, which crystallizes in the orthorhombic crystal system, has an extension of 78 mol.% Tl2WO4. The investigated systems Tl2RO4-Ag2RO4 (R = W, Mo) are similar to thallium-sodium molybdate and tungstate systems, in which the solubility regions are determined to be 60 mol.% and 86 mol. % for the high-temperature hexagonal modification of thallium molybdate and for the orthorhombic modification of thallium tungstate, respectively.
