Title (EN) METHODS FOR PROCESSING FUMED METALLIC OXIDES
(FR) PROCÉDÉS DE TRAITEMENT D'OXYDES MÉTALLIQUES SUBLIMÉS
Abstract:
(EN) Novel methods for processing fumed metallic oxides into globular metallic oxide agglomerates are provided. The methodology may allow for fumed metallic oxide particles, such as fumed silica and fumed alumina particles, to be processed into a globular morphology to improve handling while retaining a desirable surface area. The processes may include providing fumed metallic oxide particles, combining the particles with a liquid carrier to form a suspension, atomizing the solution of suspended particles, and subjecting the atomized droplets to a temperature range sufficient to remove the liquid carrier from the droplets, to produce metallic oxide-containing agglomerations.
(FR) L'invention concerne de nouveaux procédés de traitement d'oxydes métalliques sublimés en agglomérats d'oxyde métallique globulaire. La méthodologie peut permettre à des particules d'oxyde métallique sublimé, par exemple de la silice sublimée et des particules d'alumine sublimée, d'être traitées en une morphologie globulaire pour améliorer la manipulation tout en conservant une aire de surface souhaitable. Les procédés peuvent comprendre les étapes consistant à fournir des particules d'oxyde métallique sublimé, à combiner les particules avec un support liquide pour former une suspension, à atomiser la solution de particules en suspension, et à soumettre les gouttelettes atomisées à une plage de température suffisante pour éliminer le support liquide des gouttelettes, pour produire des agglomérations contenant de l'oxyde métallique.
