摘要

For some applications, piezoelectric (Pb,La)(Ti,Zr)O_3, solid solution (PLZT) thick films are screen-printed and fired on platinum-metallized Al_2O_3 sub- strates. In this work, the compatibility and adhesion between PLZT thick films, the thick film platinum electrode, and the alumina substrate was inves- tigated. Microanalysis of PLZT/Pt/Al_2O_3 structures after the firing process showed a secondary phase with B-Al_2O_3 structure at the interface between Pt and Al_2O_3, with a nominal composition of PbAl_12_O l9, doped with La_2O_3 and TiO_2 from PLZT and partly with oxides originating from impurities in alu- mina (CaO and MgO). As this compound could not be synthesized from pure oxides the results indicate that the other oxides are needed to promote the formation of a B-Al_2O_3 type compound. The formation of this compound results in significantly decreased adhesion between the PLZT/Pt layer and the alumina substrate.
