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."DISPERSIONS OF BÁRIO TITANATE". The invention provides barium titanate-based pastes, dispersions or slurries of particles in a non-aqueous medium and processes for their production. The particles have a coating comprising a metal oxide, metal hydroxide, metal hydroxide or organic acid salt of a metal other than barium or titanium. At least 90% of the particles have a particle size of less than 0.9 micrometer, when the coated particles are dispersed by a high shear mixture.
