Synthesis and investigation of textural properties of silica gels

Texture properties and structure of silica gels prepared by so-gel processing using different types of solvents and doped with Fions have been investigated by evaluating the specific surface area and pore specific volume. Solids were characterized by nitrogen adsorption at 77 K. XRD measurements were used to determine structure and scanning electron micrographs studies (SEM) were applied to observe an image of silica.
