DIELECTRIC CERAMIC COMPOSITION AND MANUFACTURING METHOD THEREOF, AND CERAMIC ELECTRONIC DEVICE |
摘要 |
Dielectric ceramic composition comprising a compound having perovskite-type crystal structure and Y-oxide, and the compound is shown by a general formula ABO3, where “A” is Ba alone or Ba and at least one selected from Ca and Sr, and “B” is Ti alone or Ti and Zr. The dielectric ceramic composition comprises dielectric particles including the above compound as a main component. When α=1000×(c/a)/d is defined, wherein “d [nm]” is an average particle diameter of raw material powders of the above compound and “c/a” is a ratio of lattice constants of c-axis and a-axis in a perovskite-type crystal structure of the raw material powders, “α” is 11.0 or less. |
