Abstract:
A process for producing a ferroelectric element of a ferroelectric material containing at least two metals, comprising the steps of:providing a solution of alkoxides of the at least two metals;hydrolyzing the metal alkoxides in the presence of a catalytic amount of a protonic acid to increase a molecular weight thereof and form a sol-like solution;adding a film-forming polymer material to the resultant sol-like solution to form a sol-like ferroelectric precursor solution;adding a binder material to the sol-like ferroelectric precursor solution to produce fine particles of the ferroelectric precursor in the sol-like ferroelectric precursor solution; andforming said ferroelectric element from the resultant sol-like ferroelectric precursor solution containing said fine particles.
