Ceramic to Metal Seals for High-Temperature Thermionic Converters

Abstract

This report covers work performed in the third three-month period of a one-year program to develop improved ceramic-to-metal seals. The objective of this program is to develop seals which are capable of long life at 1500 C in cesium and vacuum environments for use in thermionic converters, and to extend the sealing techniques developed to materials which are capable of long life at temperatures in excess of 2000 C. Work completed has enabled fabri cation of alumina-molybdenum structures which can resist a 1500 C environment. Ceramic-refractory metal systems have been identified which are stable and usable up to 2000 deg C.
