SLURRY COMPRISING MANGANOMANGANIC OXIDE PARTICLES AND DISPERSANT AND METHOD FOR THE PRODUCTION OF SUCH SLURRIES

摘要

A stable non-settling slurry of water and manganomanganic oxide particles having a particle size below 10 mum. The slurry comprises water and up to 92 wt % manganomanganic oxide particles bade on the weight of the slurry. The slurry has a pH between 9 and 11 and contains 0.05 to 0.5 wt % of a dispersant based on the weight of dry manganomanganic oxide particles. The dispersant can be an ethoxylated polycarboxylate or a polyacrylic acid salt and has a molecular weight between 500 and 50 000 g/mol.
