Abstract

Four congruently melting intermetallic compounds with the compositions Ag4Sr, Ag5Sr3, AgSr, and Ag2Sr3 respectively have been reported to exist in the silver-strontium system. In the present investigations the crystal structures of all four compounds were studied by application of X-ray diffraction techniques. The first compound was found to have the quite common CaZn5 structure and the composition is Ag5Sr rather than Ag4Sr. The structure of the second compound has orthorhombic symmetry. It was not determined but there can hardly be any doubt that it is closely related to the C32 type (AlB2 structure) and that the composition of the compound is Ag2Sr and not Ag5Sr3. The third compound also has a structure of orthorhombic symmetry and is of a type not observed previously. The composition is correctly represented by the formula AgSr. The structure is partially disordered. The structure of the fourth compound was not determined in detail. It could, however be established that it is very closely related to the AgSr structure. The composition Ag2Sr3 could be neither confirmed nor rejected. The structure has orthorhombic symmetry.
