摘要：
New values of densities rho and surface tensions sigma of liquid aluminum obtained in the range 1600 to 2360 K by contactless techniques in neutral gases are reported. Conditions for oxygen-free aluminum are fulfilled which allow determination of the surface tension of aluminum. Extrapolation to the melting point, T-m = 933 K, confirms the value of sigma(T= 933 K) = 1.05 N.m(-1).
