Abstract

The invention relates to fine-particulate zirconium titanates or lead zirconium titanates and a method for production thereof by reaction of titanium dioxide particles with a zirconium compound or a lead and zirconium compound. The titanium dioxide particles have a BET surface of more than 50 m2/g. The lead zirconium titanates can be used for the production of microelectronic components.
