| 简介 |
A ceramic material composition advantageously used as a material for a ceramic substrate containing for example a resistor such as an isolator disposed therein.
includes about 10 to 45 percent by weight of a BaO—TiO2—ReO3/2 ceramic composition, the ceramic composition being represented by xBaO-yTiO2-zReO3/2 (wherein x, y, and z each represent mole percent, 8≦x≦18, 52.5≦y≦65, and 20≦z≦40, and x+y+z=100; and Re represents a rare-earth element); about 5 to 40 percent by weight of alumina; and about 40 to 65 percent by weight of a borosilicate glass composition containing about 4 to 17.5 percent by weight of B2O3, about 28 to 50 percent by weight of SiO2, 0 to about 20 percent by weight of Al2O3, and about 36 to 50 percent by weight of MO (wherein MO represents at least one compound selected from CaO, MgO, SrO and BaO), wherein the total content of the BaO—TiO2—ReO3/2 ceramic composition and alumina is about 35 percent by weight or more. |
