COG dielectric ceramic material for low-temperature sintering thin-media multilayer ceramic capacitor
The invention discloses a low-temperature sintering thin-media nickel electrode dielectric ceramic material. The compositions of the dielectric ceramic material comprise a principal component and additives, wherein the principal component is (Ca1-xSrx)zZryO3, wherein x is more than or equal to 0.2 and less than or equal to 0.4, y is more than or equal to 0.90 and less than or equal to 1.0, and Z is more than or equal to 0.985 and less than or equal to 1.003; the additives are at least two or more compounds of Al2O3, MnCO3, MgO, TiO2, SiO2, BaCO3 and ZnO. The material is in line with COG characteristics of American EIA (Electronic Industries Association) standard, is small in particles, uniform in size distribution, good in dispersibility, and favorable in dielectric property. The material is low in sintering temperature, and uniform and compact in grain sizes when being used for manufacturing a multilayer ceramic capacitor, can realize the thickness of a dielectric layer to be less than 5mum, and is favorable in matching with a nickel internal electrode.
