Comparative Phase Equilibria in the Bi2O3-MOx-Nb2O5 Systems (MOx=Mn2O3, Fe2O3, Co3O4, ZnO)



Terrell A. Vanderah, M W. Lufaso, A U. Adler, I M. Pazos, S M. Bell


Phase equilibrium studies of the title systems all reveal the formation of non-stoichiometric, displacively disordered pyrochlore phases. Formation of other ternary phases in these systems is limited. Initial screening of the dielectric properties of the Mn, Fe, and Co pyrochlores at 100 KHz indicated lossy behavior and dielectric constants on the order of 150.
