- •
Structural and dielectric properties of pure and Nb-doped BaTiO3 ceramics strongly depends on homogenization process in solid-state reaction method.
- •
Ultrasonicated the powders at homogenization step is proposed for preparation of high purity BaTiO3 ceramics without zirconia and barium carbonate (BaCO3) impurities.
- •
Ultrasonication improves the electrical properties of BaTiO3 ceramics reducing dielectric loss.
- •
Using ultrasonication at homogenization step is helpful to obtain with the best electrical properties of the samples reducing the dielectric loss.
