玻璃陶瓷材料和层叠陶瓷电子部件
摘要：
如果使将由玻璃陶瓷材料构成的第1陶瓷层和由陶瓷磁性材料构成的第2陶瓷层层叠而成的复合层叠体共烧结，则发生玻璃成分从第1陶瓷层向第2陶瓷层扩散，其结果，第2陶瓷层的烧结性降低、绝缘电阻降低。共模扼流圈(1)所具备的复合层叠体(4)中的第1陶瓷层(2)由玻璃陶瓷材料的烧结体构成，所述玻璃陶瓷材料包含40～90重量％的玻璃和10～60重量％的填料，所述玻璃含有0.5～5重量％的K2O、0～5重量％的Al2O3、10～25重量％的B2O3、以及70～85重量％的SiO2，所述填料含有氧化铝和石英，填料中含有的氧化铝相对于玻璃和填料的合计量为1～10重量％。推测在煅烧途中氧化铝的一部分与玻璃反应，使玻璃粘度变高。
摘要（英）：

A first ceramic layer of a composite laminate included in a common mode choke coil is formed from a sintered body of a glass ceramic material. The glass ceramic material contains 40 to 90 percent by weight of a glass which contains 0.5 to 5 percent by weight of K2O, 0 to 5 percent by weight of Al2O3, 10 to 25 percent by weight of B2O3, and 70 to 85 percent by weight of SiO2; and 10 to 60 percent by weight of a filler containing alumina and quartz, and the content of the alumina contained in the filler is 1 to 10 percent by weight of the total amount of the glass and the filler.
