CERAMIC BONDED COMPACT, PROCESS FOR PRODUCING CERAMIC BONDED COMPACT, CERAMIC TEMPERATURE CONTROLLER AND CERAMIC TEMPERATURE CONTROL UNIT

摘要

A ceramic bonded compact that exhibits a high bonding strength between ceramic substrate and ceramic body and is excellent in durability. In particular, a ceramic bonded compact comprising a ceramic substrate having a conductor provided on its surface or at its internal part and, bonded thereto, a ceramic body characterized in that the ceramic substrate contains carbon and that the carbon concentration in the vicinity of the surface of the ceramic substrate is lower than that at the internal part of the ceramic substrate.
