Abstract
The present invention relates to a dielectric composition which can be densified at a temperature no higher than 1000 DEG C. and can provide ceramic products with a dielectric constant of 35 to 40 and a quality constant of 1000 to 5000 at 7 GHz. The dielectric composition comprises 0.1 to 50 wt % BaCuO2-CuO and 99.9 to 50 wt % ZrO2-SnO2-TiO2. Multilayered microwave dielectric ceramic elements can be prepared by mixing the composition of the present invention with an organic solvent, a polymer binder and a plasticizer, forming a green sheet from the mixture by tape casting, screen-printing and laminating the green sheet, and then co-firing the ceramic laminate with a metal that is high in electrical conductivity such as Au, Cu and Ag.
