Abstract
A non-lead glass for forming a dielectric, which consists essentially of, as represented by mol %, from 20 to 39% of SiO, from 5 to 35% of BO, from 2 to 15% of AlO, from 1 to 25% of CaO+SrO, from 5 to 25% of BaO, from 0 to 35% of ZnO, and from 0 to 10% of TiO+ZrO+SnO, provided that BO+ZnO is from 15 to 45%, and which does not contain alkali metal oxides, or contains such oxides in a total amount within a range of less than 1%. Further, a glass ceramic composition for forming a dielectric, which consists essentially of a Ba-containing compound powder and a powder of the above mentioned non-lead glass for forming a dielectric. Further, a dielectric obtained by firing the above glass ceramic composition for forming a dielectric.
