Influence of the Reactive Mixture Composition and Method of Treatment of Monolithic Silicon Dioxide on Its Characteristics
Monolithic porous silicon dioxide has been prepared by sol-gel method in the presence of cetyltrimethylammonium bromide and polyethylene glycol. The parameters of the porous composition and the properties of the block materials can be varied by changing the structure of the reactive mixture, conditions of re-deposition, and heat treatment conditions. The strength and permeability of materials are investigated and the optimal parameters of synthesis of monolithic porous carriers for flow-type reactors are determined.
