It is well known that porcelain containing Ti03) as a main component is widely put into practical use. However, those whose main component is barium titanate (BaTi03) have a sintering temperature of usually 1300 to 1400°C. Therefore, if this is used in a multilayer capacitor, a material that can withstand this sintering temperature must be used for the internal electrodes, such as an expensive noble metal such as platinum or palladium, resulting in high manufacturing costs. There is. In order to manufacture multilayer capacitors at low cost, it is necessary to use porcelain that can be sintered at as low a temperature as possible, especially below 1050°C, so that inexpensive metals mainly composed of silver and nickel can be used for the internal electrodes.

The present invention, in which the PbTiO3 three-component composition contains MgO as a subcomponent in an amount of 0.05% to 20% by weight based on the main component, maintains dielectric loss and resistivity at a good and practical level. However, it has a high dielectric constant and provides an excellent material as a ceramic composition for multilayer capacitors.
なお本発明の主成分組成範囲外では焼結温度が高くなっ
たり、誘電率が低下するための前述の様に限定される。It should be noted that outside the main component composition range of the present invention, the sintering temperature increases and the dielectric constant decreases, so there are limitations as described above.
