Abstract

"DISPERSõES DE TITANATO DE BáRIO". A invenção provê pastas, dispersões ou pastas fluidas de partículas à base de titanato de bário em um meio não-aquoso e processos para sua produção. As partículas possuem um revestimento compreendendo um óxido metálico, óxido hídrico metálico, hidróxido metálico ou sal de ácido orgânico de um metal que não bário ou titânio. Pelo menos 90% das partículas possuem um tamanho de partícula inferior a 0,9 micrómetro, quando as partículas revestidas são dispersas por mistura de cisalhamento alto.
