Dielectric ceramic composition and multilayer ceramic capacitor comprising same
The present invention relates to a multilayer ceramic capacitor formed by alternately stacking ceramic dielectric layers and inner electrodes (mainly comprising a base metal). The main component of the dielectric ceramic composition has a perovskite structure ABO3, the molecular formula is (KxNayLizA1-x-y-z) m (NbuTavBw) O3, and A is at least one selected from Ca, Sr and Ba alkaline earth element groups; b is selected from at least one of Ti, Zr, Hf and Sn; x, y, z, u, v and w are the mole fractions of the elements, and m is the mole ratio of the A-site element to the B-site element. 1.05, 0.95. M. 1.05, 0.95. M. 0. 05. X.0.90, 0. 05. 0.05. Y.0.90, 0.07. Y.0.90; 0.12%, 0.10%, 0.10%, 0.12%; 0 lt; u, u; 1; 0.3% by weight, 0.3% by weight; u + v + w = 1.
本发明涉及多层陶瓷电容器，通过交替堆叠陶瓷介电层和内电极(主要包含贱金属)而成。本发明介电陶瓷组合物主成分具有钙钛矿结构ABO3，分子式：(KxNayLizA1‑x‑y‑z)m(NbuTavBw)O3，A为选自Ca、Sr和Ba碱土元素组的至少一种；B为选自Ti、Zr、Hf和Sn的至少一种；x、y、z、u、v和w为各元素的摩尔分数，m为A位和B位元素的摩尔比。它们分别为：0.95.m.1.05；0.05.X.0.90；0.05.y.0.90；0.00.z.0.12；0
