Thermodynamic estimation of the stability of metal and ceramic materials in the binary $\rm Sn$–$20\%~\rm Li$ melt

The temperature dependences of nickel, iron, chromium, molybdenum, and tungsten solubility in a liquid $\rm Sn$–$20\%~\rm Li$ alloy are calculated with the thermodynamic simulation method based on information on the excess Gibbs mixing energies for a liquid phase in the form of polynomial Redlich–Kister expansion for corresponding binary systems. A thermodynamic estimation of the stability of a series of binary and ternary oxides in a liquid $\rm Li_{20}\rm Sn_{80}$ alloy at temperatures of $500$ and $800^{\circ}$C is also performed.
