Abstract

L'invention a pour objet la préparation de bioxyde de titane sous forme de particules solides séparées, sensiblement sphériques et dont la forme et la dimension sont sensiblement uniformes. On prépare en 26 un aérosol liquide comprenant des particules liquides séparées d'un composé hydrolysable de titane IV; on met en contact en 40, 44, l'aérosol avec de la vapeur d'eau en écoulement dynamique pour hydroliser le compose de titane IV en bioxyde de titane; et on recueille le bioxyde de titane. Production d'un bioxyde de titane de très grande pureté utilisable comme pigment et pour les autres usages normaux de TiO2 .
