The influence of mechanical activation on the adsorption properties of powdered tungsten

Mechanical activation in a planetary ball mill activator changes the adsorption properties of powdered tungsten. The activation leads to changes in both the adsorption energy and the concentration of active adsorption sites on the surface, thus resulting in a change in the adsorption capacity. The c...

Description
Summary:Mechanical activation in a planetary ball mill activator changes the adsorption properties of powdered tungsten. The activation leads to changes in both the adsorption energy and the concentration of active adsorption sites on the surface, thus resulting in a change in the adsorption capacity. The character and degree of the change in the adsorption properties depends nonlinearly on the duration of the mechanical effect.
