摘要：

Microemulsions in the system formamide-cetyltrimethylammonium bromide - decanol were gelled by addition of triethoxysilane and water in a molar ratio 0.5. The gelation took place both in the decanol continuous microemulsions as well as in the formamide ones with gelation time shorter in the latter. In the decanol continuous microemulsions the gelation time was reduced with increased amount of the surfactant. Gels were formed with as little as 2.5% of tetraethoxysilane corresponding to 0.7% of silica.
