Abstract

Procédé pour la préparation de cristaux cubiques de carbonate de calcium. On pulvérise tout d'abord une suspension aqueuse contenant Ca(OH)2 et des cristaux cubiques de CO3 Ca de dimensions moyennes inférieures à 0,1 mu , sous forme de gouttelettes de 0,2-2,0 mm de diamètre, dans un gaz contenant du CO2, puis l'on ajoute du Ca(OH)2 à cette suspension et on pulvérise ce mélange sous forme de gouttelettes de mêmes dimensions, dans un gaz contenant du CO2 . Application à la fabrication de cristaux cubiques de carbonate de calcium de dimensions uniformes comprises entre 0,1 et 1,0 mu environ.
