Abstract: Rheological behaviour of titania based systems prepared from the hydrolysis of titanium isopropoxide in ethanol-water mixture with different initial ratios between reagents has been studied. Rheological measurements in this study have established the dependence of gelation time upon the initial composition of raw materials. The achieved results have shown Newtonian behaviour of titania sols before gelation and non-Newtonian (pseudoplastic) behaviour after gelation. | |||||||
