The present invention provides a barium titanate dielectric powder which can form dielectric ceramic with flattened temperature characteristic of dielectric constant and excellent reliability in the high-temperature and high-electrical-field state, a method for manufacturing a ceramic green sheet, and a method for manufacturing a laminated ceramic capacitor. In the barium titanate dielectric powder of the invention, the surface of BaTiO3 powder is coated by the barium compound which contains BaCO3 and BaO with a proportion of BaCO3/BaO=0.55 in molar ratio. In the invention, the BaTiO3 powder is prepared. Then the BaTiO3 powder is soaked in aqueous solvent for more than 16 hours. Furthermore the BaTiO3 powder which is added with additives for adjusting the characteristic can be used as the BaTiO3 powder. Then the sheet forming slurry with barium titanate dielectric powder, adhesive base material and dispersion medium is prepared. Then the slurry is shaped to sheet for preparing the ceramic green sheet. |
