ABSTRACT:
Disclosed is a nonreducible dielectric composition. Provided is a highly reliable TC based dielectric composition prepared by adding a sintering additive having excellent qualities to a conventional (Ca1-xSrx)m(Zr1-yTiy)O3based dielectric composition, so that it can be sintered under a reducing atmosphere to be used in formation of a nickel electrode, can be sintered at a temperature of less than 1,300° C., and even more, at a low temperature of 1,250° C., and has a small dielectric loss and a high resistivity. The composition of the present invention includes a nonreducible dielectric composition comprising a main component expressed by the general formula, (Ca1-xSrx)m(Zr1-yTiy)O3, which has the ranges of 0≦x≦1, 0≦y<0.09, and 0.7≦m≦1.05; and 0.5-10 wt % of a minor component expressed by the general formula, aMnO-bSiO2-dR1O-eR2O2(a+b+d+e=100, R1is at least one element selected from the group consisting of Mg, Ca, Sr and Ba, and R2is at least one element of Zr and Ti), which has the ranges of 20≦a≦60, 10≦b≦65, and 0<(d+e)≦65.
