LOW FIRING DIELECTRIC CERAMIC CAPACITOR COMPOSITION

摘要

PURPOSE: Provided is a magnetic composition for dielectric sintered at low temperature, which is sintered at low temperature with reducing permittivity change against temperature so that it shows low dielectric loss ratio. CONSTITUTION: The magnetic composition is characterized by adding manganese oxide, silicone oxide and calcium oxide to main component wherein two component system of (1-X)Pb(Bi1/2Nb1/2)O3-X·Pb(Bi1/2Ta1/2)O3 with including PbO, Bi2O3, Nb2O5 and WO is configured, mixing in a ball milling method, calcining at 600 deg.C for 1 hour and burning at 650-730 deg.C for 1-3 hours.
