Dielectric ceramic composition for high frequency and dielectric resonator |
| 摘要 |
A dielectric ceramic composition for high frequency is obtained by using La and/or Nd in the main composition and iron as the additive. The main composition is expressed by the general formula<paragraph lvl="0"><in-line-formula>x(CayTiO2+y).(1-x)(LnzAl2-zO3)</in-line-formula>where Ln is at least one rare earth element containing La and/or Nd, and 0.600<=x<=0.730, 0.950<=y<=1.050, 0.980<=z<=1.030, and 0.01 to 0.5 parts by weight of iron as Fe2O3 is added to 100 parts by weight of the main composition. NiO may be comprised together with the Fe2O3.
