Dielectric Ceramic Material and Multilayer Ceramic Capacitor Using the Same

摘要

A dielectric ceramic material comprises a primary component of barium titanate (BaTiO3) and at least one additive component. The additive component has a mole percentage from 1% to 50% and is selected from the group consisting of lithium tantalite [lithium tantalate (LiTaO3)], barium cerate (BaCeO3), sodium metaniobate [sodium niobate (NaNbO3)] and the combinations thereof.

1. A multilayer ceramic capacitor, comprising:
a ceramic capacitor body, including a plurality of dielectric ceramic lavers and a plurality of inner cathode layers and inner anode layers formed along surfaces of the dielectric ceramic layers, wherein the dielectric ceramic layers are formed by sintering a dielectric ceramic mate comprising a primary component of barium titanate (BaTiO3) and an additive component, wherein the additive component has a mole percentage from 1% to 50% and has a Curie temperature more than 200° C., and the inner cathode layers and the inner anode layers are staggered arranged; an outer cathode; and an outer anode, wherein the outer cathode and the outer anode are formed on outside of the ceramic capacitor body and respectively connected electrically to the inner cathode layers and the inner anode layers.
