Titanium Dioxide (TiO2) Pigment for Paint, Coatings & Inks

Titanium dioxide (TiO 2) is the white pigment used to give whiteness and hiding power, also called opacity, to coatings, inks, and plastics. The reason for this is two-fold: TiO 2 particles of the right size scatter visible light, having wavelength λ ≈ 380 - 700 nm, effectively because TiO 2 has a …

Fig. 1 shows the XRD patterns of the Cu/TiO 2 samples synthesized by grinding Cu and TiO 2 powder in presence of ethanol. Obviously, the diffraction peaks from both anatase and rutile change very little after crude P25 powder was ground with Cu, indicating the crystal phases and sizes of TiO 2 nanoparticles were hardly affected by this mild milling process.
