The changes of the dispersive and phase composition of a Cerox type polishing material as a result of its exploitation and mechanochemical treatment are studied. A slightly expressed destruction of the solid solution CeO 2 ‐Ln 2 O 3 during the exploitation and mechanoactivation in water suspension (in centrifugal ball mill) is found out. The mechanoactivation models very well the changes of the dispersive composition of the polishing powder as a result of its use. A similarity in the behaviour of the wasted and the mechanoactivated materials is observed in the case of a treatment with HNO 3 +H 2 O 2 mixture as well.
