Abstract: The influence of manganese (Mn) addition on phase formation and microstructure of Ba(Ti1-xMnx)O3 ceramics (where x = 0.01 to 0.2) was investigated. The XRD analysis showed that the crystal structure of Ba(Ti1-xMnx)O3 at room temperature changed from tetragonal to hexagonal as Mn concentration increased. The microstructure of Ba(Ti1-xMnx)O3 ceramics at low Mn concentration revealed a bimodal feature consisting of well-grown plate like grains larger than 100 μm with low aspect ratios embedded in a fine-grained (about 3–5 μm) matrix. As the x value increased, the well-grown grains decreased with the extent of fine grains increased.
