An Electromotive-Force Study of the Activity of Aluminium in Al-Ga, Al-Ge and Al-Ga-Ge Systems

Abstract

The activities of aluminium in Al-Ga, Al-Ge and Al-Ga-Ge systems were measured between 933 K and 1273 K using an e.m.f. method with a molten salt electrolyte. The results concerning Al-Ga and Al-Ge systems are in good agreement with those previously obtained. The E(T) curves of the 36 ternary alloys studied give also some liquid-solid equilibrium tem­peratures and allow isothermal curves of the ternary liquidus surface to be drawn.
