Barium titanate oxide (BTO) is a well-known perovskite material used in various microelectronic devices thanks to its piezoelectric, pyroelectric, ferroelectric and optoelectric properties.BTO ceramics are mostly used as dielectric in the fabrication of type Ⅱ multilayer capacitors (MLCs), however, the sintering temperature of pure BTO is too high (Tsint.≥ 1400 ℃).At such temperatures, the manufacture of MLCs needs expensive electrodes in palladium (Pd) or platinum (Pt).
