Ferroelectric element, process for producing the same, and ink jet head |
摘要 |
A ferroelectric element, including a ferroelectric material containing at least two metals, the ferroelectric element having been produced by a process including the steps of: providing alkoxides of the respective metals as starting compounds; hydrolyzing the metal alkoxides in the presence of a catalytic amount of a protonic acid to increase the molecular weight; and adding a film-forming polymer material to the sol-like solution prepared in the step of increasing the molecular weight to prepare a sol-like ferroelectric precursor solution. The ferroelectric element can be formed in a thick film form without creating any cracks. It can be advantageously used as a piezoelectric element in a piezoelectric ink jet head.
