(Department of Physical Chemistry; University of Science and Technology Beijing; Beijing 100083)
Abstract: By applying algebraic formulae which correlate the density with temperature and chemical composition, computer fitting has been carried out on the the experimental data of densities for binary metallic melts.The relationship between activation energy of viscous flow, temperature and composition has been formularized analogously to that for the integral molar Gibbs energy. The semiemperical model has been successfully applied to calculate the viscosity and kinematic viscosity for various binary metallic melts.
