Dielectric ceramic composition for boundary layer condensers and a method for preparing the same

摘要

A dielectric ceramic composition having an empirical formula represented by (Srl-2xBixTil-yWy)O3 wherein x is in a range of 0.0005 to 0.003 and y is in a range of 0.0015 to 0.009 for boundary layer condensers and a method for preparing the same which are comprising the steps of: mixing Bi2O3-WO3 frit powder with main component having an empirical formula represented by Srl-2xTil-yO3 wherein x is in a range of 0.0005 to 0.003 and y is in a range of 0.0015 to 0.009, in a wet manner, the Bi2O3 frit serving as a reducing agent; drying the resulting mixture; sintering the dried mixture at a temperature of 1,400 to 1,470 DEG C under a reducing atmosphere; and applying secondary thermal treatment to the sintered body at 1,250 DEG C are disclosed.
