【 摘 要 】

On the basis of available experimental data of the state diagram Li-Ga system, thermodynamic simulation of liquidus in the system Li-Ga has been carried out with using of the model of subregular solutions. From the results of calculations energy parameters of mixture of system components in a melt have been determined and the temperature dependences of constants of melting of chemical compounds in the system have been found out. The developed calculated liquidus line of the system corresponds to the available experimental data of the state diagram. The results of the research allow determining the dependence of activities of components in melt on atomic per cent and can be used while growing monocrystals of gallium nitride in lithium flux.
