Abstract
PURPOSE: To obtain a ceramic compound enable of low temperature sintering and haivng high dielectric constant excellent of dielectric loss and dielectric strength, by adding specific amount of MnO into a compound containing specific ratio of PbO, Fe2O3, Nb2O5, MgO, WO3.
CONSTITUTION: 0.001W1.0 wt% of MnO is added into a compound containing 64.80W67.42 wt% of PbO, 5.81W11.46 wt% of Fe2O5, 9.65W19.07 wt% of Nb2O5, 0.3W2.93 wt% of MgO, 1.75W16.83 wt% of WO3. For example a material compound having said composition is wet mixed and temporarily burnt for 2 hours under 700W850°C then chemically reactioned and crushed again. Then proper amount of binder (PVA) is added and formed into a disc under approximately 3 ton/cm2 pressure thereafter it is enclosed in a magnetia ceramic container and burnt for 2 hours under approximately 850W950°C to obtain high dielectric constant ceramic body of Pb(Fe1/2Nb1/2)O3-Pb(Mg1/2W1/2)O3-MnO system.
