Abstract (en)
[origin: WO2010108988A1] The invention relates to piezoceramic compositions in the form of lead zirconate titanates (PZT), to a method for their production using fine-grained titanium dioxide particles, a fine-grained zirconium compound and a lead compound. The invention also relates to a piezoelectric component containing a lead zirconate titanate.
