| 简介 |
Disclosed is a dielectric ceramic which is capable of securing a breakdown voltage higher than 90 kV/mm, while attaining a dielectric constant ε of not less than 500. This dielectric ceramic is suitable for forming a dielectric ceramic layer of a multilayer ceramic capacitor for mid to high voltage applications. Specifically disclosed is a dielectric ceramic for forming a dielectric ceramic layer (3) of a multilayer ceramic capacitor (1), which mainly contains (Ba1-xCax)mTiO3 (0.30 ≤ x ≤ 0.50, 0.950 ≤ m ≤ 1.025). Preferably, the dielectric ceramic further contains 1-14 parts by mole of a rare earth element per 100 parts by mole of the main component, while containing 0.1-3.0 parts by mole of Mn, 0.5-5.0 parts by mole of Mg and 1.0-5.0 parts by mole of Si per 100 parts by mole of the main component. |
