Notes:
EMF of galvanic cell with zirconia –based solid electrolytes was measured to determinethe activity of Ga in liquid Ga-Sb-Tl alloys between 946 and 1233 K along the tree pseudobinarylines of Ga-(Sb/Tl), (xSb/xTl = 1/3, 1/1 and 3/1) The cell used was:Ga,Ga2O3|(ZrO2)0.92(Y2O3) 0.08|Ga-Sb-Tl, Ga2O3.The activity of Ga (aGa ) was derived by :-3EF = RT ln aGa , where E is cell potential, F is Faraday’sconstant, R is gas constant and T is cell temperature. The activity of Ga shows slight negativedeviations from ideality in the section with positive deviation from ideality in the wholecomposition range. The activity of gallium shows slight negative deviations from Raoult’s law in thesection with xSb/xTl = 3/1, moderately positive deviations in xSb/xTl =1/1 section and large positivedeviations in xSb/xTl =1/3 section
