PROBLEM TO BE SOLVED: To provide a dielectric porcelain composition for low-temperature firing that has excellent microwave properties, for example, specific inductive capacity, dielectric loss, temperature coefficient of the resonance frequency and can be fired at a temperature of 950 deg.C or lower. SOLUTION: A dielectric porcelain composition mainly containing BaO, TiO2, Nd2O3 and Bi2O3 is used as the main material and is combined with 5-20 pts.wt., per 100 pts.wt. of the main materials, of glass materials mainly containing ZnO, B2O3 and SiO2. In addition, 0-2 pts.wt. of CuO are added to the composition based on 100 pts.wt. of the main materials. In another embodiment, 0-10 pts.wt. of PbO or a glass material mainly containing PbO are also admixed to 100 pts.wt. of the main materials. |
