Role of tetraethoxysilane hydrolysis and polycondensation catalysts in synthesis of wide-pore silica gels

A study has been made of the effect of combining tetraethoxysilane hydrolysis and polycondensation catalysts operating by different mechanisms on the texture parameters of synthesized silica gels. The effect of hydrothermal treatment of a fluorine-containing silica hydrogel on the thermal stability of the xerogel texture was demonstrated.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 30, No. 2, pp. 95–98, March–April, 1994.
