High permittivity ceramic compositions |
| 摘要 |
A high permittivity ceramic composition consisting essentially of a main component expressed by the general formula: (Ba1-xMex) (Ti1-yMe'y)O3 wherein Me is Ca and/or Sr, Me' is Zr and/or Sn, x and y are respective mole fractions of Me and Me', 0.06</=x </=0.14, and 0.06</=y </=0.14; and a secondary component consisting essentially of 65 to 90 mol % of PbTiO3, 1 to 10 mol % of Pb5Ge3O11 and 1 to 30 mol % of Bi2Ti2O7, the content of the secondary component being 5 to 15 weight percent of the amount of the main component.
