The objective of this work by the Energy {ampersand} Environmental Research Center (EERC) is to assist in the development of new materials that can be used for the construction of high-temperature components in advanced energy systems. This work will include the development of data on corrosion resistance of selected high- temperature alloys and the development of a patentable technique for joining large silicon-based advanced ceramics in the field. The key to developing a successful joining technique will be the use of reactive joining compounds to lower the joining temperature without leaving continuous channels of unreacted compounds that can weaken the joint at temperatures over 1400{degrees}C or serve as conduits for transport of corrodents. Special efforts will be made in this project to transfer the developed technologies to the materials industry via licensing agreements through the EERC Foundation.
