Abstract
Two methods of hydrothermal treatment of silica gels (xerogels) in the gaseous and the liquid (under a water layer) phase - have been compar ed. The effect of these methods on the porous structure of xerogels wa s studied. It was found that the rate of hydrothermal treatment does n ot differ significantly in the gaseous and liquid phases, and it is mo st likely to be more chemical processes that occur during hydrothermal treatment in gaseous and liquid phases.
