Figure 6.12 SEM image (low voltage BSE detector, acceleration voltage 6 kV, Hitachi
S4800) of a new facade containing TiO 2 pigments. The TiO 2 particles are spread homoge-
neously over the whole facade. The average diameter of the TiO 2 particles is around 150 nm.
No sample treatment (coating) was applied. (Reprinted from R. Kaegi, A. Ulrich, B. Sinnet
