A method for producing a barium titanate-based powder that includes mixing a titanium compound and a barium compound together with water and chlorine to prepare a slurry, and temporarily firing the mixture of the titanium compound and the barium compound which is contained in the slurry to provide a barium titanate-based powder. The chlorine in the slurry is in the form of chlorine ions in a ratio of 230 to 1100 wt ppm based on the amount of the barium titanate-based powder to be synthesized.

Method for producing barium titanate-based powder, and multilayer ceramic capacitor

A method is provided which includes a reaction step of reacting at least titanium oxide, a calcium compound, and barium hydroxide in a slurry solution so as to produce a perovskite-type composite oxide. The perovskite-type composite oxide is represented by (BaCa)TiO, and x is within a range of 0&#x3c;x&#x2266;0.125. In addition, the method provides a perovskite-type composite oxide in which a water-soluble calcium compound is used as the calcium compound, and when the perovskite-type composite oxide is represented by (BaCa)TiO, x is within a range of 0&#x3c;x&#x2266;0.20.
