The present invention provides a ceramic dielectric composition having a high dielectric constant of 5,000C or higher at room temperature and sintering at a low temperature of 1150C or lower in the production of a multilayer ceramic capacitor,3In order to increase the dielectric constant at room temperature and to sinter well at low temperature, we have studied various additives and various additives. Examples The present invention relates to a process for the preparation of barium titanate (BaTiO3), Calcium oxide (7-14 molar fraction) as the second component, and copper oxide (CuO or Cu3O) 0.05-2.5 weight percent zirconium oxide (ZrO3) And manganese oxide (MnO). The above composition was sintered in barium titanate mixed with calcium stearate to obtain a dielectric constant of 8.000 or more and a loss ratio of less than 2 percent at a sintering temperature of 1300C or higher and a densification at a low temperature of 1150C, Or more and a good temperature characteristic and a loss of 2% or less. Oxides, manganese oxides, and zirconium oxide among various additives promote sintering of dielectric ceramics and reduce the dielectric cabin. In addition, manganese oxide has some effect of suppressing grain growth, having a dense structure, and reducing dielectric loss. However, the addition of too much amount of oxidation or the like causes reduction of insulation resistance, poor dielectric loss, and microstructure flare. Therefore, when the present invention is applied to the production of a multilayer ceramic capacitor, it is possible to use a low-permittivity material having a high silver content.
