AbstractIn the preparation of barium titanate powder for electronic functional ceramic, water soluble complex ion with Ba/Ti ratio of 1 is first prepared and then prepared into barium titante powder through reaction with some matter and in certain condition. The prepared barium titanate powder has Ba/Ti ratio of 1, the same as theoretic chemical value, purity of 99.8-99.99999%, average particle size of 0.05-1 mocron and is tetragonal system with space group of p=4 mm, a=0.3994 nm and c=0.4038 nm.
