Problems solved by technology

However, since Nb and Ta(Na(Nb,Ta)O 3 The starting material) is expensive, so the cost of Nb and Ta accounts for the majority of the material cost in mass production, and compared with BaTiO 3 Insulation resistance characteristics will be deteriorated compared to
[0014] Furthermore, it is known that BaTi 2 o 5 has a Curie temperature of about 500°C, but BaTi 2 o 5 Also has BaTi 2 o 5 The problem that sintering can only be performed in an air atmosphere, and also degrades reduction resistance and insulation resistance

Abstract

The invention provides a dielectric ceramic composition, a multilayer ceramic capacitor and a method for manufacturing the multilayer ceramic capacitor. The dielectric ceramic composition contains a first main ingredient of BaTiO3 and a second main ingredient of BaTi2O5, and a base material powder containing the first and second main ingredients is represented by (1-x)BaTiO3-xBaTi2O5 and x satisfies 0.1<=x<=0.8. The dielectric ceramic composition may include additional accessory ingredients, and may be used to form ceramic sheets having internal electrodes of a multilayer ceramic capacitor disposed thereon.

Description

[0001] This application claims the benefit of priority from Korean Patent Application No. 10-2016-0000827 filed in the Korean Intellectual Property Office on Jan. 5, 2016, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to a dielectric ceramic composition capable of securing X8R or X9S temperature characteristics and reliability, a multilayer ceramic capacitor including the same, and a method of manufacturing the multilayer ceramic capacitor. Background technique [0003] In general, an electronic component using a ceramic material such as a capacitor, an inductor, a piezoelectric element, a varistor, or a thermistor includes a ceramic body formed of a ceramic material, internal electrodes formed in the ceramic body, and An external electrode connected to an internal electrode on one or more surfaces of the body. [0004] Among ceramic electronic components, a multilayer ceramic capacitor in...
