Abstract
A high-frequency and low-dielectric-constant ceramic dielectric material matched with nickel internal electrode and a method for producing capacitor using same. The ceramic dielectric material consists of main crystalline phase, modifying additive and sintering flux. The main crystalline phase is MgZrSiO, wherein 0.05≦x≦0.15. The modifying additive is one or more of MnO, AlO, CaO, BiOand TiO, and the sintering flux is one or more of BO, SiO, ZnO, LiO, KO and BaO. The ceramic dielectric material has good uniformity, and excellent dielectric properties, meets the requirements of COG characteristics in EIA standard, and meets the environmental requirements. The ceramic dielectric material can be sintered under the reducing atmosphere and can be matched with nickel electrodes. The chip multilayer ceramic capacitor made of the ceramic dielectric material and nickel internal electrodes has stable performance.
