摘要：
Titanium dioxide hydrosols were synthesized by hydrolysis of titanium tetraethoxide in the presence of nitric acid with heat treatment of boiling. Concentrated (up to 40 % by weight TiO2) hydrosols were produced by repeated dispersion of the xerogels isolated by drying the sol at 100-degrees-C. The sols contained crystalline TiO2 particles in the form of a mixture of anatase and rutile with mean radius 17 nm. Thermal analysis of the xerogels was performed.
