Alkox technology of nano-, microstructured sols for ceramic materials

A method is proposed for the synthesis of a sol with a controlled particle size by influencing the parameters of the hydrolytic polycondensation process. The possibilities of sol synthesis by changing the mass, time and temperature parameters of the hydrolysis reaction of tetraethoxysilamine (TEOS), as well as a mixture of TEOS with the product of its partial hydrolysis, ethyl silicate-40 (ETS-40), in the presence of an electrophilic or nucleophilic catalyst were investigated. The size of the particles and the nature of their distribution in the synthesized samples were determined.
