Abstract
Both viscosity and self-diffusion of liquid metals obey approximately a simple form of exponential (the Arrhenius) equation.It is shown that simple empirical relationships exist between the temperature dependences (activation energy) of viscosity and self-diffusion for liquid metals and their melting points. The constant in the exponential equation can be obtained from the expressions which have been derived by authors previously.The temperature dependences of viscosity and self-diffusion of liquid metals are clasified into two groups; one is normal metals (typical metals) and the other is semi-metals.The structure factors for liquid metals can be clasified into two groups as well as the temperature dependences of viscosity and self-diffusion.Consequently, viscosities and self-diffusivities can be estimated in cases where experimental data is lacking.
