History and Challenges of Barium Titanate: Part I

2008-8-7  Traditionally, barium titanate is prepared by a solid-state reaction that involves ball milling of BaCO3 or BaO and TiO2. The mixture has to be calcined at high temperature. In some reports the needed calcination temperature was as high as 800 oC to 1200 oC [13-15], and in some other work it was 1300 oC. Barium titanate powders prepared by a solid-state reaction are highly agglomerated, with a large particle size (2-5 μm) and high impurity contents due to their inherent problems such as high reaction temperature, heterogeneous solid phase reaction, which result in poor electrical properties of the sintered ceramics. To eliminate these problems, many wet chemical synthesis routes are developed to generate high purity, homogeneous, reactive ultrafine barium titanate
