Aluminium oxide primarily used for the production of aluminium — Determination of the fine particle size distribution (less than 60 mu/m) — Method using electroformed sieves

Oxyde d'aluminium principalement utilisé pour la production de l'aluminium — Détermination de la distribution granulométrique fine (inférieure à 60 mu/m) — Méthode par emploi de tamis électroformés

Abstract / scope

The particles in the range of 63 to 16 m are quantitatively separated by sieving in an aqueous solution of a dispersing agent. The sieves are square-aperture or round-aperture electroformed sieves, depending on their origin. Each sieved fraction is dried and weighed.
