Abstract

The viscosity of selenium has been determined in the liquid state, where the rotating cylinder method was used. Experimental data show that the apparent activation energy of the viscous flow decreases with increasing the temperature. The value is 0.5 eV at the melting point and 0.26 eV at 300°C.
