The composition of the gas phase over liquid lithium at $1600$–$6000$ K in view of existence of atoms and metastable self-associates

Methods of thermodynamic simulation in view of existence of lithium atoms $(\mathrm{Li}_1)$, condensed and volatile $\mathrm{Li}_2$–$\mathrm{Li}_5$ self-associates, $\mathrm{Li}_1^+$, $\mathrm{Li}_2^+$, and $\mathrm{Li}_3^+$ ions, and $e$-gas are used to calculate partial pressures of components of the gas phase over liquid lithium in the $1600$–$6000$ K temperature range and the thermal characteristics of the system at $1600$ and $6000$ K.
