Glass ceramic composition, glass ceramic sintered body, and multilayer ceramic electronic component
Abstract:
A glass ceramic composition which is formed by firing into a sintered body having a relatively high relative dielectric constant and Q value is provided. It includes a CaZrO3-based ceramic and a Li2O—MgO—ZnO—B2O3—SiO2-based glass. The Li2O—MgO—ZnO—B2O3—SiO2-based glass is 1 to 12 percent by weight of the total composition, the content of Li2O is 3.5 to 15 percent by weight, the content of MgO is 20 to 50 percent by weight, the content of BaO is 0 to 25 percent by weight, the content of CaO is 0 to 10 percent by weight, the content of SrO is 0 to 25 percent by weight, the content of B2O3 is 16 to 29 percent by weight, the content of SiO2 is 11 to 35 percent by weight, the content of ZnO is 5 to 20 percent by weight, and the content of Al2O3 is 0 to 15 percent by weight. This glass ceramic composition is advantageously used for green glass ceramic layers to form a green laminate structure useful as a main component body of an LC filter or the like.
Abstract(Chinese):
