DIELECTRIC COMPOSITION AND MULTI-LAYER CERAMIC ELECTRONIC PARTS FABRICATED BY USING THE SAME

摘要

The present invention relates to a dielectric composition and a multi-layer ceramic electronic component using the same; the present invention comprises a dielectric grain having a perovskite structure represented by ABO_3, and provides the dielectric composition that, when an imaginary line from the center of the dielectric grain to the grain boundary exists, the content of rare-earth elements in the range of 0.75-0.95 from the center of the dielectric grain is 0.5-2.5 at% compared to 100 at% of ions forming a B site. The multi-layer ceramic electronic component using the dielectric composition according to the present invention has great reliability and secures a high dielectric constant.
