Low-temperature sinterable ceramic composition and multilayer ceramic substrate

摘要

A low-temperature sinterable ceramic composition which can be simultaneously sintered with a low melting point metal, such as silver or copper, and which has a preferable combination of high strength and superior electrical characteristics. The low-temperature sinterable ceramic composition is formed by mixing a ceramic component comprising an MgO crystal phase and an MgAl2O4 crystal phase and a glass component composed of 13 to 50 wt % silicon oxide, 3 to 30 wt % boron oxide, and 40 to 80 wt % alkaline earth oxide.
