Effect of divalent chloride salts on lamellar silica conductivity

Silica is an important raw material in the production of soluble silicates, silicon and its derivatives: silicon carbide and silicone, which are converted into the lamellar form using the sol-gel process. This compound, which has been extensively studied because it is structurally organized, can be used for selective adsorption of toxic substances or immobilization of photo-active species. Impedance spectroscopy was used in a study of the electrical properties of lamellar silica doped with the following metal salts: nickel chloride, manganese chloride, and copper chloride, in order to observe the cation effect in their structure. In this study, the following order of conductivity was obtained: manganese chloride nickel chloride copper chloride. This effect was also observed using X-ray diffraction analysis.
