Beschreibung
Zusammenfassung:	A ceramic and metal bonded composite comprises an intermediate metal plate (20) interposed between a ceramic member (10) and a metal member (18) and brazed thereto. The intermediate metal plate (20) carries on its junction surface a central square projection having substantial area, pins arranged near the four corners and fins between the corners. The central square projection mechanically and thermally couples the ceramic and metal members (10, 18) together with the brazing layer (14) and the pins and fins also mechanically and thermally couple both members together with the brazing layer (14), while permitting relative displacement between both members (10, 18) through their plastic deformation, thereby preventing cracks from generating in the ceramic member (10).
