Influence of strontium on manganese-doped barium titanate ceramics
Source abstract
Abstract
Abstract The influence of Sr on the crystal structure, microstructure, and thermal expansion of Ba 0.98 Sr 0.02 Ti 1− x Mn x O 3 ceramics (0≤ x ≤0.02) was investigated. Compared to Sr-“free” samples the transition region between tetragonal and hexagonal phase is shifted to significant higher Mn concentrations. Mn contents higher than 2.0 mol% strongly hinder grain growth at 1400°C. The Goldschmidt tolerance factor is used to discuss the stabilization of the tetragonal phase by the Sr impurity.
