Abstract
Official abstract text for this publication.
The problem addressed lies in providing a dielectric composition having a relatively high dielectric constant of 800 or greater when a DC bias of at least 8 V/μm is applied, and also in providing a dielectric element employing said dielectric composition, an electronic component, and a laminated electronic component. [Solution] A dielectric composition in which the composition of the main component is in accordance with the following formula (1): (Bi a Na b Sr c )(Mg d Ti 1-d )O 3 (1) [where a, b, c and d satisfy the following: 0.10≦a≦0.65, 0<b≦0.45, 0<c≦0.85, 0<d<0.20, and 0.95≦a+b+c≦1.05].
First claim
Opening claim text (preview).
The invention claimed is: 1. A dielectric composition in which the composition of the main component is in accordance with the following formula (1): (Bi a Na b Sr c )(Mg d Ti 1-d )O 3 (1) characterized in that a, b, c and d satisfy the following: 0.10≦a≦0.65, 0<b≦0.45, 0<c≦0.85, 0<d<0.20, and 0.95≦a+b+c≦1.05. 2. The dielectric composition as claimed in claim 1 , wherein a, b, c and d satisfy the following: 0.10≦a≦0.65, 0.01≦b≦0.45, 0.01≦c≦0.85, 0.01≦d≦0.16, and 0.95≦a+b+c≦1.05. 3. A dielectric element comprising the dielectric composition as claimed in claim 1 . 4. An electronic component provided with a dielectric layer comprising the dielectric composition as claimed in claim 1 . 5. A laminated electronic component having a laminated portion formed by alternately laminating an internal electrode layer and a dielectric layer comprising the dielectric composition as claimed in claim 1 .
