Conversion of Alkoxide Solutions to Oxides: Evaporation of Products
Abstract
The evaporation kinetics of methanol depended on the drying rate achieved by flowing dry air over the gel. Cracking of the gel during drying was used to indicate the degree of stress. At low drying rates, minor cracking was observed near the edges of the gel. At high flow rates, extensive cracking was observed. Keywords: Drying, Gels, Evaporation kinetics, Diffusion, Sol-gel processing, Silicon tetramethoxide, Tetramethylorthosilicate, Ceramic film processing, Metallo-organic-solution deposition, Solution processing.
