Abstract : A tin-solution calorimeter, described in earlier reports, was employed for the measurement of enthalpies of solution and formation of various alloys. Using a technique permitting the direct measurement of the partial quantities for each component, detailed values were obtained for the heats of solution of tin in a range of liquid silver-tin alloys; some corresponding values for the silver partial and for the integral quantities have also been obtained. Studies of the heats of solution of rare earth materials in liquid tin continued. New measurements were made with ytterbium and praseodymium, and earlier values for cerium and lanthanum were recalculated in the light of more recent specific heat data. (Author)
