Abstract: A dielectric ceramic composition includes about 10% to about 40% by weight of BaO, about 20% to about 65% by weight of SiO2, about 6% to about 40% by weight of Al2O3, about 1% to about 15% by weight of B2O3, about 0.3% to about 3% by weight of Cr2O3, and about 1% to about 40% by weight of ZrO2. A multilayer ceramic substrate has a laminated structure including an inner layer portion and outer layer portions that have a smaller thermal expansion coefficient than that of the inner layer portion. The use of the dielectric ceramic composition for the outer layer portions enables the ceramic to be resistant to erosion caused by a plating liquid used for plating external conductive films, thus maintaining good adhesiveness between the external conductive films and the outer layer portions.
Abstract translation: 介电陶瓷组合物包括约10重量％至约40重量％的BaO，约20重量％至约65重量％的SiO 2，约6重量％至约40重量％的Al 2 O 3，约1重量％至约15重量％ 的B 2 O 3，约0.3％至约3％的Cr 2 O 3，和约1％至约40％的ZrO 2。 多层陶瓷基板具有包括具有比内层部分的热膨胀系数小的内层部分和外层部分的层压结构。 通过使用电介质陶瓷组合物作为外层部分，陶瓷能够抵抗由用于镀覆外部导电膜的电镀液引起的侵蚀，从而保持外部导电膜与外层部分之间良好的粘接性。
