Influence of the adsorbed molecules on dielectric properties clinoptilolite
1.Introduction Zeolites represent the materials which crystal structure looks like alumosilicate a skeleton penetrated by cavities and channels of the molecular sizes 1 .In the last usu ally there are molecules of water and cations the metals,compensating negative charge alumooxgen tetrahedrons.Strictly periodic system of identical channels and cavities in zeolites allows to use them as adsorbents,molecular a sieve and catalysts.Studying of electric properties of porous systems were spent in the beginning of the XX-th century 2,however till now questions on existence of through ionic conductivity of zeolites,its mechanisms and the nature of carriers of a charge remain disputable.Presence loosely coupleds cations and water molecules in channels leads to great values of dielectric permeability on low frequencies and essential dependence of electric properties of zeolites on frequency and temperatures.In the literature there is an experimental material about a role ion-exchange cations as active centres of adsorption on zeolites.It is supposed,that than it is more poorly connected KaTHOH with a lattice,especially vigorously it co-operates with adsorbed molecules.
