The Influence of Parameters in Silica Sol- Gel Process

Abstract

The sol-gel process is an inorganic polymerization considered a promising route for the design of new materials for optical, electrical, (bio)- medical, and solar energy applications. Special attention is focused on the design of silica-based material by of sol-gel process. The aim of the paper is to investigate, in order to understand, the role of some important parameters (precursors type, pH, catalysts, temperature, etc.) in sol-gel routes. It is proved that the textural and structural material properties are strongly influenced by synthesis and processing parameters.
