Microstructural Characterization and Dielectric Properties of Barium Titanate Solid Solutions with Donor Dopants
TLDR
In this paper, the dielectric properties of 1.0 mole% Ta 5+ doped BaTiO3 solid solution were investigated and the transition temperature of this solid solution was ∼110 o C.Abstract:
5+ were investigated. The dielectric properties were analyzed and the relationship between the properties and structure of doped BaTiO3 was established. The fine-grain and high density of the doped BaTiO3 ceramics resulted in excellent dielectric properties. The dielectric properties of this solid solutions were improved by adding a small amount of dopants. The transition temperature of the 1.0 mole% Ta 5+ doped BaTiO3 solid solution was ∼110 o C with a dielectric constant of 3000 at room temperature. At temperatures above the Curie temperatures, the dielectric constant followed the Curie-Weiss law.read more
