shows microstructure developments of silica-coated BaTiO3 powders at various levels. There was observed some discernible progress as the SiO2 content increased. The powder agglomeration decreased with increasing silica content. At 5.0 wt.% SiO2, the powder exhibits a uniform distribution without agglomeration. This disappearance of agglomeration could be due to the electrostatic repulsion between the coated silica layers on the surface of BaTiO3 particles.
