Subsolidus grain growth in donor doped barium titanate
- 73 Downloads
Grain growth in donor doped BaTiO3 was studied below the temperature of liquid phase formation. It was found that a high donor concentration and high oxygen partial pressure effectively inhibit grain growth rate during sintering. Defect chemistry, derived from a model consistent with electrical measurements, well describes the grain growth properties of donor doped BaTiO3 in the subsolidus grain growth region.
