Abstract

Thin films and dispersed products in the system SiO 2 -P 2O 5 with phosphorus oxide molar content from 0 to 30% have been obtained by the sol-gel method from film-forming solutions based on tetraethoxysilane and phosphoric acid, ethyl alcohol, and water. The variations of the rheological properties in successive states of the solution - sol-gel system are established. The physical - chemical processes in solution with deposition on a substrate and with heat-treatment of the product are investigated. IR spectroscopy and atomic-force microscopy are used to study the structure and physical - chemical properties of the films and disperse products obtained.
