Abstract

The multicomponent alloy systems containing group III and V elements are particularly important for their electrical and optoelectronic applications. An accurate knowledge of their thermodynamic properties provides the essential tool in the determination of the phase equilibria which will be useful in processing the semiconducting materials. It may be mentioned that Zbitnew et al. [1] studied the quaternary system using x-ray Debye Scherrer powder photographic technique and x-ray fluorescence for the lattice parameter measurements and the chemical analysis respectively. They have shown that there is complete miscibility between Al-Sb, Ga-Sb, and InSb compounds which results in the formation of isomorphous pseudoternary solid solutions. Thermodynamic modelling of the quaternary system has been carried out by Sharma et al. [2] using a quasi sub-sub regular solution model based on the available information of the constituent binary and ternary properties. In the absence of any activity data, the present investigation measures the activities of Al in the liquid Al-Ga-In-Sb system using a concentration cell of the type.
