Handbook of Sol-Gel Science and Technology

Abstract

In the present chapter, the basics of thermal analysis and the most appropriate thermal investigation methods of gels, glasses, and powders obtained by sol‐gel procedure are presented. Representative data obtained by applying these methods for the mono- and polycomponent gels and powders obtained both by alcoholic and aqueous route are given. The differences that occur between the thermal properties of the materials obtained by the two methods of preparation are underlined. In both cases, it was established that the thermal methods corroborated with other structural investigations (XRD, FT-IR, Raman) allow obtaining information not only about the thermal behavior but also on the chemical composition of the as-prepared gels and powders. Information given by the thermal analysis methods used in order to establish the experimental conditions to transform the gels into (bulk) glasses and to determine their glass transition and crystallization temperature were also discussed.
