Claims7
A composition for forming a piezoelectric containing a dispersoid obtained from metallic compound, wherein the content of hafnium contained in the composition is 3,000 ppm or less.
A method for producing a piezoelectric film comprising the steps of:
- coating a substrate with a composition for forming a piezoelectric containing a dispersoid obtained from metallic compound, in which the content of hafnium is 3,000 ppm or less, to form a coating film;
- drying the coating film;
- and
- sintering the dried coating film to obtain a piezoelectric film.
