P Billik, G Plesch
Materials Letters, 2007•ElsevierThe synthesis of titanium dioxide phases rutile and anatase via mechanochemical reaction
and subsequent annealing of the products was studied. TiOSO4· xH2O and anhydrous
Na2CO3 powders in the molar ratio 1: 1 were used as starting reactants. The Na2SO4·
xH2O by-product was removed by simple water washing process. The synthesis of
nanocrystalline rutile is almost complete after 60 min milling and particles with average size
of 15 nm were obtained. Nanoparticles of anatase with average size of 5–35 nm were …

The synthesis of nanocrystalline rutile is almost complete after 60 min milling and particles with average size of 15 nm were obtained. Nanoparticles of anatase with average size of 5–35 nm were obtained after 5 min milling and subsequent annealing at 300–600 °C.
