Phase equilibria and dielectric properties of Bi3+(5/2)xMg2−xNb3–(3/2)xO14−x cubic pyrochlores
Subsolidus pyrochlores with the proposed formula, Bi 3+(5/2)x Mg 2−x Nb 3−(3/2)x O 14−x (0.14≤x≤0.22) were successfully synthesised at the firing temperature of 1025°C using conventional solid-state reaction. The excess Bi 3+ charge was offset by removal of relative proportion of Mg 2+ and Nb 5+ tog...
