Title (EN) INORGANIC MATERIAL SLURRY
(FR) BOUILLIE D'UN MATERIAU INORGANIQUE
Abstract:
(EN) There is disclosed a high solids, aqueous suspension of a cationically dispersed particulate inorganic material, characterised in that the particulate inorganic material has a particle size distribution such that not more than 10 % by weight of the particles have an equivalent spherical diameter (esd) smaller than 0.25 microns.
(FR) On décrit une suspension aqueuse à teneur élevée en solides, d'un matériau inorganique particulaire dispersé de manière cationique, qui se caractérise en ce que le matériau inorganique particulaire présente une distribution granulométrique telle que les particules dont le diamètre sphérique équivalent (dse) est inférieur à 0,25 micron ne dépassent pas 10 % en poids.
