<p>A multi-layer ceramic capacitor is prepared from a novel ceramic composition produced from the oxides of lead (PbO), iron (Fe203), niobium (Nb2O5), nickel (NiO), and tungsten (WO3), or the synthesized compounds (Pb(Fe1/2Nb1/2) O3. Pb(Fe2/3W1/3)O3 and Pb(Ni1/3Nb2/3)O3, together with a small quantity of a Mn(N03)2 solution to improve certain electric properties of the capacitor. When used in the correct proportions the oxides disclosed herein are capable of producing monolithic ceramic capacitors having Z5U ratings. In particular, the lead, nickel, niobate compound tends to flatten and to lower the curie peak for the ceramic composition.</p> |
