Calculation of the adsorption potential of argon on dehydroxylated Aerosil

Abstract

The adsorption potential of argon on an amorphous solid such as dehydroxylated Aerosil has been calculated by considering a model of the solid that takes into account only two characteristics: the stoichiometry and the sizes of its atoms. The adsorption potential has also been calculated for the crystalline solids tridymite and cristobalite. The values are compared with those from experiments on the adsorption of argon on dehydroxylated Aerosil in the intermediate adsorption zone.
