EMF Study of the Thermodynamic Properties of Gallium Selenide Ga2Se3. 188... 

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 thermodynamic properties of the gallium selenides have not been much studied. The purpose of the present investigation was to study the thermodynamic properties of Ga28e3 by the emf method described in [9, 10].

The physical properties of bismuth, summarized in Table 1, are characterized by a low melting point, a high density, and expansion on solidification. Thermochemical and thermodynamic data are summarized in Table 2. The solid metal floats on the liquid metal as ice floating on water. Gallium and antimony are the only other metals that expand on solidification. Bismuth is the most diamagnetic of the metals, and it is a poor electrical conductor. The thermal conductivity of bismuth is lower than that of any other metal except mercury. 

With aqueous solutions in pressurised cells, the temperature can be varied in a very broad range. Many fundamental electrochemical data have been obtained in this medium. Thermodynamic quantities such as activity coefficients of ions [252], equilibrium double-layer capacity [261], zeta potential of metals [233], potential-pH diagrams [206] or properties of the palladium-hydrogen electrode were determined [262]. Exotic systems, e.g. the solvation of rare earth atoms in liquid gallium [234], have been studied. Main research interests in subcritical aqueous solution were focused on the kinetics, reaction mechanism and transport properties.
