Capacitor has a dielectric ceramic body consisting of (in parts. wt.) : ceramic material (I) 100; and an additive mixt. of B2O3, SiO2 and Li2O (II), 0.2-10.0 (I) has a compsn. ((Ba1-x-yCax Sry)O)K(Ti1-ZZr)O2 where x=0.02-0.27, y=0-0.37 (not zero), z=0-0.26 (not zero), K=1.00- 1.04, and 1-x-y-0.60-0.98. Electrodes are pref. of a base metal, esp. Ni and are buried in the dielectric body. Dielectric has a high dc breakdown voltage, pref. at least 25V per micron (claimed); also sintering temp. is low anough to cosinter the ceramic with the buried electrodes.
