  • Microwave dielectric ceramic compositions
    Patent number: 4550089
    Abstract: A microwave dielectric ceramic composition consisting of 15-19 mol % of barium oxide (BaO), 61-73 mol % of titanium dioxide (TiO.sub.2), 3.5-15 mol % of samarium oxide (Sm.sub.2 O.sub.3), and 1.5-15 mol % of cerium oxide (CeO.sub.2). Since this composition has a high specific dielectric constant .epsilon..sub.r and a high no load value Q, it can be used as a microwave resonator, a temperature compensating capacitor or the like.
