摘要： 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.
