Abstract

For the studies described, the sol-gel matrices were prepared by way of acid hydrolysis. Thin films were produced in the form of thin layers covering the microscopic glasses. The optical microscope was used for examination of the sol-gel glass surfaces. The sol-gel materials produced from TEOS with various molar ratios R (ratio of the number of solvent moles to the number of TEOS moles) have been examined. The microscopic images were acquired by a computer and their Sobel transforms were calculated. The analysis of the experimental data showed that the sol-gel prepared with the molar ratio equal to 32 (R=32) are stable, do not crack and have smooth surface.
