| 摘要 |
The dielectric magnetic composition is prepared by (A) blending lead monoxide (PbO), zinc oxide (ZnO), niobium pentaoxide (Nb2O5), tungsten trioxide (WO3), manganese dioxide (MnO2), barium titanate (BaTiO3) and strontium titanate (SrTiO3) into a quaternary composition of 0.38-0.5 mol% Pb(Zn1/3 Nb2/3)O3 0.35-0.42 mol% BaTiO3 - 0.08-0.12 mol% SrTiO3 - 0.06-0.1 mol% Pb(Zn1/2W1/2)O3, and (B) adding 0.05-0.2 wt.% mnanganese dioxide (MnO2) to the quaternary composition. Produced composition has stabilized temperature characteristic and can be sintered at the temperature of 1100 deg.C or less. It is used to manufacture laminated condenser using Ag-Pd inside electrode.
