Beschreibung
Zusammenfassung:	The present invention deals with precursor composition for alkaline earth metal containing ceramic layers. In particular, the present invention pertains to a precursor composition containing:(i) one or more soluble compounds of transition metals (ii) one or more soluble compounds of alkaline earth metals (iii) one or more soluble compounds of rare earth metals (iv) difluorinated carboxylate and/or partly fluorinated propionates (v) one or more solvents, wherein the difference between the boiling points of the corresponding acid of the components (i) to (iii) to the boiling point of component (iv) is less than 60 K. La présente invention porte sur une composition de précurseur pour des couches en céramique contenant un métal alcalino-terreux. En particulier, la présente invention concerne une composition de précurseur contenant : (i) un ou plusieurs composés solubles de métaux de transition, (ii) un ou plusieurs composés solubles de métaux alcalino-terreux, (iii) un ou plusieurs composés solubles de métaux de terres rares, (iv) un carboxylate difluoré et/ou des propionates partiellement fluorés, (v) un ou plusieurs solvants. La différence entre les points d'ébullition de l'acide correspondant des constituants (i) à (iii) et le point d'ébullition du constituant (iv) est inférieure à 60 K.
