摘要：

Microwave dielectric properties and microstructures of BaPr2Ti4O12 and BaPr2Ti5O14 ceramics which have extremely similar crystal structures, were investigated, including those of the solid solution represented by the formula of Ba-(6-x)Pr8+2x/3Ti18O54 ceramics. It is suggested that BaPr2Ti5O14 ceramics are composed of mixed phases, approximately 85.0 vol. % Ba4.05Pr9.3Ti18O54 (x = 1.95), 8.1 vol. % TiO2, and 6.9 vol. % BaTi4O9. The microwave dielectric properties of the Ba6-xPr8+2x/3Ti18O54 system are strongly dependent on the x value, which is interesting for studying the relationship between microstructures and dielectric properties. Far infrared reflection spectra were also measured to study the mixed phases formed in these ceramics in more detail.
