Title:
誘電体セラミック用ゾル組成物と、これを利用した誘電体セラミック及び積層セラミックキャパシタ
Document Type and Number:
Japanese Patent JP4255448
Kind Code:
B2
Abstract:
Disclosed herein is a sol composition for ultrathin dielectric ceramic films, and dielectric ceramic and a multilayered ceramic capacitor manufactured using the same. The sol composition, composed of BaTiO3 as a main ingredient and an auxiliary ingredient, includes a polymeric sol having a metal precursor solution of BaTiO3 and an organic solvent, and an organic additive dissolved in the organic solvent to act as the auxiliary ingredient, in which the amount of the organic additive corresponds to the required amount of the auxiliary ingredient of the dielectric ceramic. Further, the ultrathin dielectric ceramic film, which is manufactured by a sol-gel process, includes the auxiliary ingredient, and hence, is advantageous in making low temperature sintering possible, and having a high dielectric constant, a high sintered density, and TCC characteristic meeting the X5R of EIA standard.
