Pokraskin Titanium dioxide flakes are produced by breaking down a continuous film of TiO2 [8, 12]. The most efficient process is therefore a web-coating process involving a thermal hydrolysis of TiOCl2 on the web. Alternative procedures are the application of titanium alkoxide on a smooth flat surface and cracking the resulting film into flakes by steam treatment or the application of a TiO2 sol on a glass surface and scratching off the resulting film [13, 14].
The titanium dioxide flakes produced by these methods are not single crystals but quite porous and, lacking the mechanical support of a substrate, hence brittle. Therefore, they are not yet used in technical applications in which mechanical stress is exerted.
The TiO2 flakes can be reduced to titanium suboxides yielding a dark bluish mass tone in addition to the interference color [15].
