抄録

An adiabatic calorimeter used for specific heat measurements was improved for the measurements of heats of mixing. Heats of mixing in the binary liquid alloys consisting of silver and aluminum, gallium, indium, thallium, germanium, tin, lead or bismuth were determined at 970°C. The experimental data obtained were represented by the following ξ function.<BR>(Remark: Graphics omitted.)<BR>The main results obtained are as follows.<BR>(1) Some systematic correlations were found between heats of mixing and positions of the considered couples on the periodic table.<BR>(2) Behavior of heats of mixing seems to be explained qualitatively in terms of the electronegativity, size and valence factors. Each factor has an intimate relation with the periodic table.<BR>(3) Heats of mixing have intimate relations with phase diagrams, suggesting that the atomic bonding in liquid silver alloys is similar to that of solid.<BR>(4) The ξ function of silver alloys having secondary solid solutions in a solid phase decreases markedly with increasing silver concentration. Hence it is considered that the interaction energy depends considerably on the silver concentration.
