Part 1. production of binders for ceramic industry using Sol-Gel method. 3. hydrolysis and Sol-Gel transformation in ethylsilicate binders free of organic solvents

摘要

The results of physicochemical study of hydrolysis and sol-gel transformation in ethylsilicate binders free of organic solvents are presented. The effect of the type and quantity of acidic catalysts, water/ethylsilicate ratio on the heat ofhydrolysis reaction, sol-gel transition and properties of binders are considered. The IR-spectra of gels obtained from hydrolysates upon fast and slow hydrolysis are presented. Technological aspects of binder production are considered.
