Originální abstrakt

A sol of silicon dioxide has been used for modeling of the interactions of calcium salt with SiO2-H2O in high dispersive system. The dependence of the zeta potential on concentration of calcium acetate in SiO2-H2O system has been characterized at lower concentration of acetate by negative values. Isoelectric point has been determined at ratio molar concentration of acetate to silicon dioxide r= c(calciumacetate)/c (SiO2)=0,347. This work is focused on determination of optimum condidtions for gelation, control of sol stability and explaining of gelation mechanism by ion exchange on silica surface.
