Zusammenfassung:	Cerium oxide powder or zirconium oxide powder is mixed with a) an alkali metal or ammonium salt of the condensation product of napthalene sulphonic acid with formaldehyde, or of lignin sulphonic acid serving as an anionic deflocculating agent in an amount necessary to cause deflocculation, b) an electrolyte containing a metal cation having a valency greater than 1, and c) water, to form a slurry in which the powder is in a state of reversible flocculation.
