Abstract： |
The present invention is material for laminated ceramic capacitor with high temperature stability and basic material inner electrodes. The inner electrode is made of low cost metal, such as Ni, Cu and their alloy. The dielectric material comprises BaTiO3 as main component, and additives in cludes CaO, CaTiO3, BaO, SiO2, SrO2, MnO2, MgO, Co2O3, Co3O4, Fe2O3 and Y2O3 as well as one or more RE oxide and salt in certain proportion and is prepared through mixing, sintering in reducing atmosphere of mixed nitrogen and hydrogen. The dielectric has excellent performance, including room temperature dielectric constant of 2000-3000, etc. The material of the present invention is suitable for producing great capacity superthin laminated ceramic capacity with high insulating resistivity and stable performance. |
