摘要:
The dielectric ceramic composition of the first aspect of the invention comprises an essential component having a compositional formula of xBaO-yTiO2-zNd2O3 (wherein 0.02≦x≦0.2, 0.6≦y≦0.8, 0.01≦z≦0.3, x+y+z=1), and contains two types of glass powder, one comprising PbO, ZnO and B2O3 and the other comprising SiO2 and B2O3, and a third component that comprises Al2O3, SrTiO3, GeO2 and Li2O. Its advantages are that it can be sintered at low temperatures, its dielectric constant &egr;r falls between 10 and 50 or so, its unloaded Q is large, and its temperature-dependent resonant frequency change is small. The dielectric ceramic composition of the second aspect of the invention comprises an essential component having a compositional formula of s(xBaO-yTiO2-zNd2O3)-tNd2Ti2O7 (wherein 0.02≦x≦0.2, 0.6≦y≦0.8, 0.01≦z≦0.3, x+y+z=1, 0.1≦s≦0.8, 0.2≦t≦0.9, s+t=1), and contains two types of glass powder, one comprising PbO, ZnO and B2O3 and the other comprising SiO2 and B2O3, and a third component that comprises Al2O3, SrTiO3, GeO2 and Li2O. Its advantages are that it can be sintered at low temperatures, its dielectric constant &egr;r falls between 10 and 50 or so, its unloaded Q is large, and its absolute value of a temperature coefficient of resonant frequency &tgr;f is small. Still another advantage of the composition is that its relative dielectric constant &egr;r, its unloaded Q and its temperature coefficient of resonant frequency (&tgr;f) can be controlled in any desired manner by controlling the Nd2Ti2O7 content of the composition.
