In this paper, the structures, phase transformations, and dielectric properties of pyrochlore ceramics containing bismuth were studied, and the relation between the orthorhombic and cubic pyroglores in the Bi2O3-ZnO-Nb2O5 (BZN) system was investigated.Abstract:
The structures, phase transformations, and dielectric properties of pyrochlore ceramics containing bismuth were studied. The relation between the orthorhombic and cubic pyrochlores in the Bi2O3-ZnO-Nb2O5 (BZN) system has been investigated. The effect of bismuth in distorted cubic pyrochlore structures is discussed. BZN compositions with pyrochlore structures have excellent dielectric properties, very low dielectric loss, and high dielectric constants with stable frequency and temperature dependence.read more
