A series of extremely homogeneous Si-Ge solid solution alloys were prepared by the horizontal zone-melting technique. The materials of various compositions were used to make accurate deter minations of density, lattice parameter, phase equilibria, and band gap as functions of composi tion. The densities of about 100 samples were determined to an accuracy of 0.1 by the method of Archimedes. The solidus temperatures were determined at intervals of 5-10Si by the DTA method, and the results confirm the original 1939 phase diagram of Stohr and Klemm.
