Title:
DIELECTRIC COMPOSITION, DIELECTRIC CERAMIC AND CAPACITOR
Document Type and Number:
Japanese Patent JP2017193476
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dielectric composition which has a desired dielectric constant, has good temperature characteristics of an electrostatic capacitance, is excellent in voltage resistance to a high AC voltage, prevents breaking of a base even when high temperature load is applied to the dielectric composition, has little change in the electrostatic capacitance, and has high reliability.SOLUTION: A dielectric composition contains titanium calcium silicate and calcium titanate. When a content of the titanium calcium silicate is represented by a mol%, a content of the calcium titanate is represented by b mol%, and a content of a compound containing manganese is represented by c mol%, relationships of 23.4≤a≤75.0, 21.0≤b≤76.4, c≥0.21 and a+b+c=100 are held. When a content of the titanium calcium silicate is represented by d mol%, a content of the calcium titanate is represented by e mol%, and a content of a compound containing vanadium is represented by f mol%, relationships of 23.0≤d≤61.7, 37.9≤e≤76.8, f≥0.16 and d+e+f=100 are held.SELECTED DRAWING: None
