The occurrence of compound formation in Mg-Sb and Cu-Sb liquid alloys has been discussed through investigation of concentration-dependent thermodynamic and microscopic functions such as Gibbs free energy of mixing, G_M/RT, concentration-concentration fluctuations in the long wavelength, S_cc (0), Warren-Cowley short range order, α₁ and chemical diffusion. Using the compound formation model, results suggest that Mg₃Sb₂ and Cu₂Sb compounds are formed in Mg-Sb and Cu-Sb systems respectively. It is also observed that the tendency for compound formation is greater in Mg-Sb than Cu-Sb system.
