Characterization of Ba<inf>0.77</inf>Sr<inf>0.23</inf>TiO<inf>3</inf> powder prepared from an oxalate co-precipitation and an impregnation method
Barium titanate (BaTiO3) powder was prepared from an oxalate co-precipitation method with the starting precursors of barium chloride dihydrate and potassium titanium oxalate dihydrate with mole ratio of 1: 1. Precipitated powder was obtained after adding oxalic acid until the pH of the final solutio...
