Abstract

Procédé de préparation de microsphères céramiques, consistant à : mélanger une huile non miscible à une solution aq. d'un composé métallique hydrosoluble et ayant un point d'ébullition > à celui de l'eau dans cette solution aq., conjointement avec un émulsionnant; appliquer des vibrations ultrasoniques à cette solution pour former une émulsion de type eau/huile dont la dimension des gouttelettes est réglée en modifiant une fréquence de ces vibrations ultrasoniques [intervalle de 10kHz à 100 kHz]; chauffer cette émulsion à une T< au point d'ébullition de l'eau pour évaporer l'eau libre des gouttelettes dans lesquelles le composé métallique hydrosoluble est dissous et afin de disperser les particules sphériques de ce composé métallique hydrosoluble dans la phase d'huile; et chauffer ensuite la solution dispersée à une T> à la T à laquelle le composé métallique hydrosoluble est décomposé pour former un oxyde métallique, tout en étant cependant < à la T à laquelle commence la croissance des grains dans cet oxyde métallique, évaporant et décomposant ainsi cette huile, tout en en éliminant celle-ci, pour obtenir de la sorte les microsphères d'oxyde métallique précitée
