发明名称 REDUCTION RESISTANT DIELECTRIC SUBSTANCE AND CERAMIC CAPACITOR FOR TEMPERATURE COMPENSATION
摘要 PROBLEM TO BE SOLVED: To provide a dielectric substance having excellent reduction resistance which enables the increase of Q value of a ceramic capacitor for temperature compensation by using Ni or an Ni alloy for an internal electrode, and further enables reduction of the cost of the capacitor. SOLUTION: The reduction resistant ceramic dielectric substance for temperature compensation has a composition containing, by mass, 0 to 45% calcium titanate, Al2 O3 and SiO2 by 2 to 20% in total and one or more kinds selected from MnO, Cr2 O3 , Fe2 O3 , CoO and NiO by 0.1 to 1.0% in total, and the balance magnesium titanate of at least 50%. Further, the ceramic capacitor for temperature compensation is obtained by using the above ceramic as a dielectric substance, and Ni or an Ni alloy as the internal electrode.
