Activity measurements of magnesium in liquid Ag-Mg solutions were carried out at 1573, 1673. 1773 and 1823 K using two different techniques. While most measurements were carried out using the vapor pressure method at 1573 and 1673 K, a number of measurements were made at 1773 and 1873 K using the gas equilibration technique. The latter method was used mostly for obtaining Ag-Mg solution at very low Mg contents. It was found that magnesium had a negative deviation from ideality in Ag-Mg solutions. The excess Gibbs energy of Ag-Mg solutions seemed to have a quite weak temperature dependency in the temperature region studied. The excess Gibbs energy of Ag-Mg solution can be described as;
