Formation of Compounds in the Ag2O–Sb2O3–MoO3 System on Heating

Аннотация

This paper presents a detailed study of phase formation processes in the AgNO₃–Sb₂O₃–MoO₃ system during heating in air. The compositions of the solid-state reaction products have been determined using thermogravimetry and qualitative X-ray diffraction. The results demonstrate that, at a final heat treatment temperature of 1023 K, synthesis yields a range of Ag_2–xSb_2–xMo_xO₆ compounds with the pyrochlore structure and 0.0 ≤ x ≤ 2.0. The structural parameters of the synthesized phases have been refined by the Rietveld method in space group Fd3̅m and their electrical conductivity has been measured.
