Dielectric ceramic composition

摘要

A dielectric ceramic composition of high dielectric constant and low dielectric loss, which can be co-fired with Ag electrodes, is provided for use in various parts of electric and electronic appliances. Based on a base composition with a high dielectric constant, the composition comprises glass frit and optionally CuO, as represented by the following formula:wherein, 13.0 mol %<=x<=20.0 mol %; 10.0 mol %<=Y1+y2<=17.0 mol %; 6.0 mol %<=w<=11.0 mol %; 60.0 mol %<=z<=67.0 mol % with the proviso that x+y1+y2+w+z=100; 85.0 wt. %<=a<=97.0 wt. %; 3.0 wt. %<=b<=15.0 wt. %; and c<=7.0 WT. %.
