Abstract:

A diphenyl ether calorimeter and a liquid-tin solution calorimeter were employed to determine selected thermodynamic properties of Group III and V elements and their compounds. The enthalpy and heat capacity of eight Group III-V compounds were determined in the solid state. The compounds are InP, InAs, InSb, GaP, GaAs, GaSb, AlP, and AlSb. Data were obtained on the enthalpy and heat capacity of the liquids of several of these compounds. The heat of fusion was then calculated for these several compounds. The heats of solution of the elements Al, Ga, In, P, As, and Sb and the compounds GaSb, InP, InAs, and InSb in tin were determined. From these data the heats of formation of the same compounds were determined. Author
