Alkoxo-Technology of Nano-Micro-Structured Sols for Ceramic Materials

A method is proposed for synthesizing sol with controlled particle size by influencing the parameters of the hydrolytic polycondensation process. The possibility of synthesizing sols by changing the mass, time and temperature parameters of the hydrolysis reaction for tetraethoxysilane (TEOS) as well as a mixture of TEOS with a product of its partial hydrolysis — ethylsilicate-40 (ETS-40) — in the presence of an electrophylic or nucleophylic catalyst is studied. The particle sizes and distribution in the synthesized sample are determined.
