Abstract:
Microwave dielectric properties and microstructures of BaPr 2 Ti 4 O 12 and BaPr 2 Ti 5 O 14 ceramics which have extremely similar crystal structures, were investigated, including those of the solid solution represented by the formula of Ba 6− x Pr 8+2 x /3 Ti 18 O 54 ceramics. It is suggested that BaPr 2 Ti 5 O 14 ceramics are composed of mixed phases, approximately 85.0 vol. % Ba 4.05 Pr 9.3 Ti 18 O 54 ( x = 1.95), 8.1 vol. % TiO 2 , and 6.9 vol. % BaTi 4 O 9 . The microwave dielectric properties of the Ba 6− x Pr 8+2 x /3 Ti 18 O 54 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.
