A simple thermodynamic approach is considered to investigate the temperature dependence of the chemical diffusion coefficient in binary liquid alloys exhibiting miscibility gaps. Application is made to Bi-Zn, Cd-Ga and Al-In which show non Arrhenius behaviour which is significantly marked in the critical region.
