Abstract
The changes of the dispersive and phase composition of a Cerox type po lishing material as a result of its exploitation and mechanochemical t reatment are studied. A slightly expressed destruction of the solid so lution CeO2-Ln(2)O(3) during the exploitation and mechanoactivation in water suspension (in centrifugal ball mill) is found out. The mechano activation models very well the changes of the dispersive composition of the polishing powder as a result of its use. A similarity in the be haviour of the wasted and the mechanoactivated materials is observed i n the case of a treatment with HNO3 + H2O2 mixture as well.
