摘要
Disclosed is a method for fabricating a piezoelectric/electrostrictive thick film, using a seeding layer. On a substrate is formed the seeding layer which is prepared from a ceramic sol solution or a ceramic paste, both identical or similar in composition to the piezoelectric/electrostrictive film. The ceramic paste is prepared from a mixture of a ceramic oxide powder, which has a particle size of 5 &mgr;m or less and is prepared from Pb and Ti-based piezoelectric/electrostrictive elements by a non-explosive oxidation-reduction combustion reaction at 100-500° C., and a ceramic sol solution in water or an organic solvent, identical or similar in composition to the ceramic oxide powder. Then, the seeding layer is subjected to an after-treatment. A piezoelectric/electrostrictive film is directly formed on the seeding layer. Alternatively, a piezoelectric/electrostrictive film, separately formed and sintered, is attached on the seeding layer.
