The solubilities of silicon and germanium in liquid gallium and in indium were determined over a wide temperature range. If the logarithms of the solubilities are plotted against the inversed absolute temperatures, straight lines are obtained the slopes of which yield the heats of solution. For the investigated systems it was found that the heats of solution are approximately proportional to the third power of the radii of the solvent atoms. Upon slow cooling of the saturated solutions silicon and germanium crystals of fair purity were obtained. The solubility data are of interest for the preparation of junction transistors.
