ABSTRACT:
The invention provides a method for producing a lead zirconate-lead titanate ceramic material (PZT ceramic) that exhibits higher fired density than conventional PZT ceramics and approximately equal electrical properties. The method employs zirconium oxide sol, containing extremely small zirconium oxide particles, as a raw material.
