Dielectric ceramic composition for low temperature sintering

摘要

A dielectric ceramic composition for low temperature sintering according to the invention is a composition which is a solid solution having two components of Pb(Ni1/3 Nb2/3)O3-PbTiO3 and at least one additive component of Pb(Zn1/2 W1/2)O3 and Pb(Cu1/3 Nb2/3)O3, and the mol percents of the components fall within the following ranges: Pb(Ni1/3 Nb2/3)O3 75.0-85.0; PbTiO3 0-15.0; at least one of Pb(Zn1/2 W1/2)O3 and Pb(Cu1/3 Nb2/3)O3 5.0-16.5. Further, at least one of oxides of Mn, Mg, and Ca below 0.5 mol percent may be added to the above composite.
