GLASS-CERAMIC COMPOSITION, SINTERED GLASS-CERAMIC, AND LAMINATED CERAMIC ELECTRONIC COMPONENTS

摘要

The invention provides a glass-ceramic composition capable of giving a sintered body having a fairly high relative permittivity and a fairly high Q value by firing. A glass-ceramic composition comprising a CaZrO₃ ceramic and an Li₂O-MgO-ZnO-B₂O₃-SiO₂ glass wherein the Li₂O-MgO-ZnO-B₂O₃-SiO₂ glass accounts for 1 to 12wt% of the whole composition and comprises 3.5 to 15wt% of Li₂O, 20 to 50wt% of MgO, 0 to 25wt% of BaO, 0 to 10wt% of CaO, 0 to 25wt% of SrO, 16 to 29wt% of B₂O₃, 11 to 35wt% of SiO₂, 5 to 20wt% of ZnO, and 0 to 15wt% of Al₂O₃. This composition can be advantageously used in green glass-ceramic layers (10 to 20) of a green laminated structure (8) which is a precursor for producing the body of an LC filter component.
