Gd compositions with Bi, Sb, Si, B, P and Se, and Hf compounds with Si and B have been examined for their potential as thermoelectric materials. Seebeck potentials, resistivities and melting points have been determined. Several refractory systems have been uncovered, with melting points as high as 3000 C, and compounds in the Gd-Se systems have demonstrated a possible value as a thermoelectric material. In the Gd-Se system Seebeck outputs as high as 500 microvoltC have been obtained but this and resistivities have been found to vary unconventionally with treatment and mild variations in composition.
