Dielectric ceramic composition. |
| 摘要 |
<p>A dielectric ceramic composition having a composition (mole%) expressed by the formula xMgO.yLa2O3. xTiO2 wherein x, y and z are numerals that lie within a range surrounded by a line that couples the points a, b, c, d and e in Fig. 1. The composition can contain 0.01 to 3% by weight of MnO2 with respect to chief components consisting of the above three components. The composition can be effectively used as a resonator or a circuit board in the microwave regions. <IMAGE></p> |
