Abstract

Ceramics of solid solution compositions in the system BaTi1−x−ySnxZryO3 have been fabricated using conventional mixed oxide processing routes. Samples with y = 0 or 0.01 exhibited maximum relative permittivities, ε r max of ~ 65000 and ~ 62000 respectively. The Curie peaks became broader and ε r max decreased with increasing zirconium substitutions. The Curie temperature decreased linearly from 35°C for y = 0 to −40°C for y = 0.11: for the latter, ε r max was equal to ~ 20000. The results are interpreted on the basis of microstructural features and on the degree of compositional inhomogeneity in the system.
