发明名称 METHOD FOR PRODUCING DIELECTRIC FILM, METHOD FOR PRODUCING PIEZOELECTRIC ELEMENT, METHOD FOR PRODUCING LIQUID-JET HEAD, DIELECTRIC FILM, PIEZOELECTRIC ELEMENT, AND LIQUID-JET APPARATUS
摘要 A method for producing a dielectric film, comprising: a coating step of coating a colloidal solution containing an organometallic compound containing a metal constituting a dielectric film containing at least a lead component to form a dielectric precursor film; a drying step of drying the dielectric precursor film; a degreasing step of degreasing the dielectric precursor film; and a firing step of firing the dielectric precursor film to form a dielectric film, and wherein the drying step includes a first drying step of heating the dielectric precursor film to a temperature lower than the boiling point of a solvent, which is a main solvent of the material, and holding the dielectric precursor film at the temperature for a certain period of time to dry the dielectric precursor film, and a second drying step of drying the dielectric precursor film at a temperature in the range of 140° C. to 170° C., the degreasing step is performed at a degreasing temperature of 350° C. to 450° C. and at a heating-up rate of 15 [° C./sec] or higher, and the firing step is performed at a heating-up rate of 100 [° C./sec] to 150 [° C./sec].
