Abstract

L'invention concerne des suspensions, des dispersions ou des coulages de particules à base de titanate de baryum dans un milieu non aqueux et des procédés de fabrication correspondants. Lesdites particules ont un revêtement qui comprend un oxyde métallique, un oxyde métallique hydraté, un hydroxyde métallique ou un sel d'acide organique de métal autre que le baryum ou le titane. Au moins 90 % des particules ont une taille inférieure à 0,9 micromètre lorsque les particules revêtues sont dispersées par mélange à cisaillement élevé.
