Spherical Ba 0.96 La 0.04 TiO 3 powders were synthesized by a wet chemical method-based on a precipitation process, able of controlling uniformity and particle size. After sintering, fine-grain Ba 0.96 La 0.04 TiO 3 ceramics with good dielectric properties were obtained. Different synthesis routes of Ba 0.96 La 0.04 TiO 3 ceramics were used, and their effects on microstructure and dielectric properties were examined. Results showed that the ceramics samples prepared by La 3+ and Ba 2+ added together (abbreviated as, BLT-T) resulted in a mixture of large and small grains, sharp permittivity peaks, and high dielectrics loss. By comparison, another ceramics samples prepared by La 3+ and Ba 2+ added separately (BLT-S) exhibited uniform grain size and broadened/flattened permittivity peaks. The high value of ε r (3255) and low tan δ (0.01) at room temperature and negligible temperature coefficient of capacitance from − 35 to 85 °C suggested the suitability of the above materials for multilayer capacitor applications.
