| Abstract: | Effect of method of titanium dioxide hydrogel precipitation from TiCl4 and NH4OH solutions on the properties of 0.0025–0.44 M hydrosols prepared by exposure to ultrasound radiation was studied. The hydrosols was shown to contain primary particles united into aggregates with average size 22–120 nm irrespective of hydrogel precipitation method. The method of hydrogel precipitation affects the size and porosity of the aggregates in the hydrosols. |
