particles as passive nthner et al. 2007 ; Kraus et al. 2009 ). In this case, the

precursor acts as a binder between the particles and the ceramic

fillers (G ü

fillers reduce the
shrinkage of the coating. The used slurry for coating applications consists typically
of a precursor, a solvent, ceramic particles (e.g., ZrO 2 ,Al 2 O 3 , SiC, Si 3 N 4 ,B 4 C,
BN), and additives to homogenize and to stabilize the suspension. Figure 12 shows
