LOW TEMPERATURE SINTERING DIELECTRIC COMPOSITION AND MULTILAYER CDERAMIC CAPACITOR
The present invention relates to a low temperature sinterable dielectric composition and a multilayer ceramic capacitor. According to one embodiment of the present invention, the suggested low temperature sinterable dielectric composition comprises BaTiO_3 as a main component; and a secondary component including 1.0 to 2.0 mol% of BaCO_3, 0.5 to 1.0 mol% of a rare-earth oxide which is at least one selected from the group consisting of Y_2O_3, Ho_2O_3, Dy_2O_3, and Yb_2O_3, 0.1 to 1.0 mol% of a manganese oxide (MnO), and 1.0 to 2.0 mol% of a borosilicate-based glass, with respect to 100 mol% of the main component. According to one embodiment of the present invention, a low temperature sinterable dielectric composition satisfying a characteristic of a temperature range of X7R without including Ca in the main component, and a multilayer ceramic capacitor using the low temperature sinterable dielectric composition as a dielectric can be produced.
