Bi- Based Pyrochlore Ceramics and Their Microwave Properties

This paper represented microstructure and micowave dielectric properties of Bi - based pyrochlore dielectric ceramics with low firing temperature. Taking Bi2O3 - ZnO - Nb2O5 and quarternary systems solid solution ceramics for example, They were selected as a model representative of Bi - pyrochlores, their phase structure, phase transfonnation, microwave properties and their modified methods were described in detail. The synthesis processes, evaluation techniques fundamentally in the laboratory and methods to further lower firing temperature were presented. Finally, their development in the future was discussed.
