摘要： A dielectric ceramic composition having an empirical formula represented by (Sr.sub.l-2x Bi.sub.x Ti.sub.l-y W.sub.y)O.sub.3 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 Bi.sub.2 O.sub.3 -WO.sub.3 frit powder with main component having an empirical formula represented by Sr.sub.l-2x Ti.sub.l-y O.sub.3 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 Bi.sub.2 O.sub.3 frit serving as a reducing agent; drying the resulting mixture; sintering the dried mixture at a temperature of 1,400 to 1,470.degree. C under a reducing atmosphere; and applying secondary thermal treatment to the sintered body at 1,250.degree. C are disclosed.
