Composition for ceramic substrate and ceramic circuit component

摘要

There is disclosed a composition for a ceramic substrate, comprising a mixture of: powdered borosilicate-based glass comprising 5% to 17.5% by weight of B2O3, 28% to 44% by weight of SiO2, 0% to 20% by weight of Al2O3, and 36% to 50% by weight of MO (where MO is at least one selected from the group consisting of CaO, MgO, and BaO); and a powdered ceramic; in which the amount of the powdered borosilicate-based glass being 40% to 49% by weight based on the total amount of the composition for a ceramic substrate, and the amount of the powdered ceramic being 60% to 51% by weight based on the total amount of the composition for a ceramic substrate.
