An investigation was made of the thermodynamic properties of gallium phosphide using the emf method in the temperature range 320 430 K. The experimental results were used to calculate the free energy, dhe endialpy and the entropy of formation, as well as the absolute entropy and the energy of atomization of gallium phosphide at 298 K. 

The thermodynamic properties are needed in the selection of suitable conditions for the synthesis of this compound and of elements which can be used to dope it. Therefore, we determined the principal thermodynamic functions associated with the formation of gallium phosphide. This was done using the emf method and a liquid electrolyte. 

The chemical properties of the binary rare-earth phosphides have been studied fully only for monophosphides, their thermodynamic characteristics have also been determined. Thermodynamic data of formation and atomization of the R monophosphides are listed in table 19.
