The Influence of Cr2O3 and NiO on the Phase

The anatase-rutile conversion was investigated by heating titanium dioxide in the temperature range from 20 C to 1100 C. As a result, it was established that the chromium and nickel oxides additions lower the onset temperature of the phase transformation and accelerate it. Get price

Low

2014/12/15TiO 2 has three crystalline forms: rutile, anatase and brookite . Anatase titania usually exhibits higher photocatalytic activity than rutile and brookite, owing to its higher density of localized states, the surface-adsorbed hydroxyl radicals and slower charge carrier recombination [5] – [7] .

Critical Review of Public Health Regulations of Titanium

2014/8/4Therefore, rutile and anatase are the only important crystal structures of TiO 2 used in commercial products (DuPont 2007). The refractive index is 2.56 and 2.49 for anatase and 2.60 to 2.61 and 2.89 to 2.90 for rutile (Phillips and Griffen 1981). Anatase is a much Get price

Impact of anatase and rutile titanium dioxide

TiOSUB2/SUB microparticles are widely used in food products, where they are added as a white food colouring agent. This food additive contains a significant amount of nanoscale particles; still the impact of TiOSUB2/SUB nanoparticles (TiOSUB2/SUB-NPs) on gut cells is poorly documented. Our study aimed at evaluating the impact of rutile and anatase TiOSUB2/SUB Get price

Preparation of Phase

In the second method hydrolysis was carried out using (NH 4) 2 SO 4 as an additive. It can be seen that the hydrolysis of TiCl 4 under high acidic conditions promotes the growth of rutile phase of TiO 2, where as hydrolysis in presence of (NH 4 ) 2 SO 4 hold up the formation of rutile phase resulting in the formation of anatase form of TiO 2 .

2020/8/29Although both anatase and rutile titanium dioxide pigments are lightfast, exposure to light can cause a phototropic reversible blue-gray discoloration on the surface in some circumstances. The tendency of the early pigments to blush or redden on exposure to bright light was attributable to impurities and was eliminated by improved processing. Get price
