Abstract. The sol-gel method has recently become significant in the area of materials chemistry. The importance of undergraduate laboratory experience in the synthesis and characterization of sol-gel silicates has been emphasized in several publications. In this article the introduction of the fractal dimension for the structural characterization of sol-gel silicates is shown to be useful for helping undergraduate students understand the global structure of sol-gel silicates as well as their growth phenomena.

Key Words: In the Classroom; inorganic chemistry; sol-gel silicates; fractal dimension
