Study of the solid–liquid equilibria in the Ga–In–As–Sb system at 973 and 1073 K

Activities of Al in the Al+Ga+Bi+Sb system in the temperature range (1173 to 1323) K

“…In order to obtain various derivatives of activity coefficient of the components as shown in the stability functions, molar excess free energy of the system is expressed as [4,5], …”
