ABSTRACT:
The invention relates to fine-particled alkaline-earth titanates and to a method for the production thereof by reacting alkaline-earth metal compounds with titanium dioxide particles. The titanium dioxide particles have a BET-surface greater than 50 m2/g. The titanium dioxide particles can have a very low sulphate, chloride and carbon content. The reaction can take place at a temperature below 700° C. The alkaline-earth titanate can have a BET-surface of 5-100 m2/g. Advantageously, it does not contain any hydroxyl groups in the crystal lattice. The alkaline-earth titanate can be used in the production of microelectronic components.
