MFCD00011269,MFCD00210650. Titanium(IV) oxide, Aeroxide(R) P25, Thermo Scientific - Fisher Sci The results showed that P25 contains more than 70% anatase with a minor amount of rutile and a small amount of amorphous phase. The composition anatase/rutile/amorphous could be determined by analysis of P25 mixed with an internal standard, nickel (II) oxide. Download : Download full-size image; Fig. It is well known that P25 is composed of anatase and rutile crystallites, the reported ratio being typically 70:30 or 80:20, but it seems that nobody knows the exact crystalline composition [2], presumably due to a lack of methodology for determination of crystalline contents in nanometer-sized particulate samples [3]. 130 Moisture* 2 hours at 105 °C wt.% < 1.5 Ignition loss 2 hours at 1000 °C, based on material dried for 2 hours at 105 °C wt.% < 2.0 pH in 4% dispersion € 3.5 - 4.5 Titanium dioxide based on ignited material wt.% > 99.50 Al 2 O 3 - content … to DIN EN ISO 787/11, Aug. 1983 g/l approx. All the syntheses and photocatalytic tests were carried out in Millipore Milli-Q ultrapure water as medium. Both particle types have been investigated previously in cell cultures under submerged conditions. Product Safety Information Evonik Operations GmbH Product … TiO 2 is even used in foodstuffs.
