摘要： The method is carried out in the following manner: An aqueous mixture solution containing barium chloride and titanium chloride is added into an aqueous oxalic acid solution, so that barium titanyl oxalate would be precipitated. Then the precipitates are aged, washed and filtered. The filtered barium titanyl oxalate precipitates are crushed, and dried. Then a thermal decomposition is carried out to obtain a agglomerated barium titanate powder, and this is crushed again to obtain the final barium titanate powder. In order to obtain barium titanate based powder such as Ba(Ti1−zZrz)O3, (Ba1−xCax)(Ti1−zZrz)O3, and (Ba1−x−yCaxSry)(Ti1−zZrz)O3, the desired elements (Ca, Sr, Zr and so on) are added to barium titanyl oxalate when crushed before thermal decomposition step. After thermal decomposition and crushing, the barium titanate based powder can be obtained.

摘要： There are provided a conductive paste composition for an inner electrode, and a laminated ceramic electronic part and a manufacturing method thereof using the conductive paste composition. The conductive paste composition includes metal powder coated with an organosilica compound formed by polymerization of an organosilane compound having a structure of RnSi(OR′)4-n (wherein R is selected from alkyl and aryl groups, each having 20 or less carbon atoms, R′ is any one of the alkyl groups having 4 or less carbon atoms, and n is 1 or 2). Since the organosilica coating layer is coated around the metal powder particles, preventing the metal powder particles from being agglomerated, thereby allowing the conductive paste composition having very superior dispersibility to be manufactured. In addition, effects such as inhibited oxidation of the metal powder during plasticization and effectively inhibited shrinkage of the metal powder during sintering may be accomplished.
