Barium titanate (BaTiO3) was synthesized by the oxalate method with the starting precursors as barium chloride and potassium titanium oxalate with mole ratio of 1:1. Precipitate was obtained after adding oxalic acid until the pH of the final solution was 4. The precipitate was milled and calcined at 700 oC for 2h. Mn-doped barium titanate (BaMnTiO3) was prepared by the impregnation method. Barium titanate calcined at 700 oC was mixed with 2 and 4 mole % of Mn from manganese chloride. The mixed powder was calcined at temperatures of 800 oC and 900 oC for 2h. The phase of BaMnTiO3 was studied by X-ray diffraction (XRD). Hexagonal structure of Ba(Mn0.33Ti0.67)O2.84 was obtained after calcination at 900 oC for 2h with 2 and 4 mole % of Mn. The morphology and chemical composition were investigated by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The particle size of Ba(Mn0.33Ti0.67)O2.84 powder was in the range of 50-60 nm with irregular in shape. The elemental composition of barium, manganese, titanium and oxygen showed the characteristic X-ray energy values.
