Abstract
An isoperibol liquid metal solution calorimeter in which samples are introduced below the surface of the melt is described. Enthalpies of solution in liquid bismuth at ca. 625°K in kcal mol−1 were found to be +0.99 ± 0.05 for copper, −1.41 ± 0.08 for indium, and −1.16 ± 0.07 for tellurium.Enthalpies of formation in kcal mol−1 at 625°K of cubic cuprous selenides are −7.98 ± 0.20 for Cu1.80Se; −7.80 ± 0.19 for Cu1.85Se; −5.92 ± 0.20 for Cu1.90Se; −5.29 ± 0.20 for Cu1.95Se; and −5.21 ± 0.14 for Cu2.00Se.Keywords
