Solid rare gases alloyed with metals

Since this is the quantity most usually calculated by approximate theoretical models (lO) it is of considerable interest to evaluate Si(Q,u)) and to compare this with the full S(Q,u) for a given model. In the following sections we consider in turn the application of the MD technique to Rare Gas Solids (13), Alkali Halides (lU), Metals (15,l6) and Alloys (17) and Molecular Crystals (l8,19). 

Ttvo roles of the interconnect in high-temperature solid oxide fuel cells (SOFCs) are the electrical connection between cells and the gas separation vvithin the cell stack. The fact that the interconnect must be compatible with all of the cell components as well as be stable with respect to both oxidising and reducing gases places very stringent materials requirements on it. These requirements plus the additional constraints of cost and ease of fabrication tend to limit the possible choices to only a few materials. These materials come from either perovskite-type oxide ceramics based on rare earth chromites for operating temperatures in the 900-1000°C range or metallic alloys for lower temperature cell operation.
