DIELECTRIC CERAMIC COMPOSITION FOR LOW-TEMPERATURE SINTERING AND HOT INSULATION RESISTANCE AND MULTILAYER CERAMIC CAPACITOR USING THE SAME

摘要

A dielectric ceramic composition for low-temperature sintering and hot insulation resistance (hot IR) is capable of carrying out low-temperature sintering, improving a hot IR characteristic, and meeting X5R characteristics, and a multilayer ceramic capacitor makes use of the dielectric ceramic composition. The dielectric ceramic composition includes a main component BaTiO₃, and sub-components, based on 100 moles of the main component, MgO of 0.5 moles to 2.0 moles, Re₂O₃ of 0.3 moles to 2.0 moles, MnO of 0.05 moles to 0.5 moles, V₂O₅ of 0.01 moles to 0.5 moles, BaO of 0.3 moles to 2.0 moles, SiO₂ of 0.1 moles to 2.0 moles, and borosilicate glass of 0.5 moles to 3.0 moles, where Re includes at least one selected from the group consisting of Y, Ho and Dy.
