Abstract

As part of calorimetric studies on metals and alloys at high temperature, heat contents of the III-V compounds of AlN, GaN, AlP, GaP, InP, AlAs, GaAs, InAs, AlSb, GaSb and InSb were measured over the temperature range 650 to 1550K using a drop calorimeter. The heat content and the heat capacity equations for the solid compounds were derived by the use of the Shomate function. Heat contents of the Ga-As, In-As, Ga-P and In-P binary alloys were also measured to derive the thermodynamic quantities of these liquid alloys by the use of a therniodynamic analysis method, and the vapour pressure-temperature-composition diagrams were constructed.
