Abstract

An improved sealing composition for use between alumna ceramic parts, or between alumina ceramic and refractory metal, consists of 32-42 weight percent CaO, 13-19 weight percent BaO and no more than 1 weight percent MgO, balance A12O3. The composition has a lower liquidus temperature (1325 DEG C) than an otherwise similar one previously used which included 5% MgO, and its thermal expansion coefficient is less affected by dissolved A12O3. As a result, a closer thermal match with alumina ceramic can be maintained during seal processing and the rejection rate is reduced. <IMAGE>
