Phase formation in the BaCO3–PbO–Fe2O3–Nb2O5 system

Features of the formation of lead-ferroniobate compounds in the x BaCO 3 –(1 – x )PbO–Fe 2 O 3 –Nb 2 O 5 system by solid-phase synthesis are investigated. For perovskite-type lead-ferroniobate solid solution, a single-phase concentration region is revealed at 1233 K. The crystalline structures of th...

Zusammenfassung:Features of the formation of lead-ferroniobate compounds in the x BaCO 3 –(1 – x )PbO–Fe 2 O 3 –Nb 2 O 5 system by solid-phase synthesis are investigated. For perovskite-type lead-ferroniobate solid solution, a single-phase concentration region is revealed at 1233 K. The crystalline structures of the synthesized compounds are refined using Rietveld analysis and the Pm 3̅ m and R 3 m space groups. Ceramic samples of lead ferroniobate are studied by scanning electron microscopy.
