FINE-PARTICLED ALKALINE-EARTH TITANATES AND METHOD FOR THE PRODUCTION THEREOF USING TITAN OXIDE PARTICLES

摘要

Preparation of alkali earth titanate (I) comprises reaction of alkali earth metal compounds with titanium dioxide particle with a BET surface of more than 50 m 2>/g. Independent claims are also included for: (1) a preparation comprising titanium oxide hydrate particle and a water-soluble alkali earth compound, where the molar ration of titanium and alkali earth metal is 0.95-1.05; (2) (I), which is prepared by the preparation method; (3) preparation of a microelectronic element comprising (I), which is grounded and subsequently pressed to a green body, subsequently sintered; and (4) a microelectronic element comprising (I).
