Abstract
A colloidal dispersion of a metal chalcogenide material in divided state in an aqueous liquid phase selected from the group consisting of aqueous solutions and solutions including a mixture of water and at least one solvent that is miscible with water, wherein the carbon element of the material is present in a proportion of less than 2.5 wt. % as determined by elemental analysis, the concentration of the material in the colloidal dispersion is more than 40 g/l, and the colloidal dispersion has a charge potential value which is negative and the absolute value of which is higher than 20 mV.
