Dielectric ceramic composition |
摘要 |
Disclosed is a dielectric ceramic composition consisting essentially of a main component of (Sr1-xKX)2 (Na1-xBix)Nb5O15 with x being from about 0.1 to 0.35, and containing at least one of Cr, Mn, Fe, Co and Ni in an amount of from about 0.02 to 2.0% by weight relative to the main component and in terms of CrO2, MnO2, Fe2O3, CoO and NiO. The composition contains neither Pb nor Ba, but has a specific inductive capacity comparable to that of BaTiO3-type dielectric materials. The temperature-dependent variation in the specific inductive capacity of the composition is low. The composition is suitable for use in capacitors.
