Barium titanate nanopowders prepared from the modified oxalate co-precipitation method

Barium titanate nanopowders were prepared from the modified oxalate co-precipitation method. Barium chloride dihydrate and potassium titanyl oxalate dihydrate were used as the starting precursors with the mole ratio of Ba:Ti as 1:1. Barium titanyl oxalate complex powders were obtained after adjustin...

Barium titanyl oxalate complex powders were obtained after adjusting the final of pH of the solution to 1. The precipitates were filtered, washed and dried at 100 °C for 5h. The precipitate powders were calcined at 400-700 °C for 2h. The phase transition was studied by X-ray diffractometry (XRD).
