On the Influence of Chemical Modification of Silica on Its Porous Structure under Solvothermal Conditions

Sidorchuk V. V., Skubiszewska-Zięba J., Charmas B., Leboda R.

Polish Journal of Chemistry

2008

Vol. 82, nr 1-2

183-190

Changes of porous structure of silica gels (aerosilogels) were studied during their chemical modification under various conditions, i.e. solvothermal at high temperature and pressure of reagents as well as in common treatment with substances of different chemical character without high pressure. Necessity of taking into account the effects of transfer of silica mass during its modification under the conditions of high pressure of modifying agent (organothermal treatment) on its porous structure parameters was pointed to.
