圧電性材料を製造する方法 |
摘要 |
The invention concerns a method for preparing a material based on piezoelectric ceramic oxide(s) comprising the following steps: a) wet deposition on at least one surface of a substrate of a layer of a dispersion comprising a piezoelectric ceramic oxide powder and a piezoelectric ceramic oxide precursor sol-gel solution identical to or different from the piezoelectric oxide constituting the powder; b) repeating a) once or several times, so as to obtain a stack of at least two layers; c) heat-treating said layers so as to transform them into corresponding ceramics; d) wet-shrink impregnation of the stack obtained at c) with a sol-gel solution identical to the one used in step a); e) optionally repeating step d) once or several times; f) heat-treating said stack, so as to transform the sol-gel impregnating the stack into the corresponding piezoelectric ceramics. |
