Ceramic capacitors and dielectric compositions.

摘要

A dielectric composition comprising a ternary system of non-stoichiometric lead magensium niobate, non-stoichiometric lead zinc niobate and non-stoichiometric lead iron niobate up to 10 wt % PbO may be added to the ternary mix. Compositions with firing temperatures in the range 950 to 1040°C, have dielectric constants in the range 13900-22100 making the composition particularly suitable for high silver content multilayer ceramic capacitors.
