The effect of the mechanoactivation on Y 2 O 3 , Nd 2 O 3 and CeO 2 , on mixtures of La 2 O 3 with each of these oxides as well as on the solid solutions La 2 O 3 –CeO 2 is studied. The activation causes a decrease of the individual oxides' unit cell parameters. The formation of solid solutions of La2O 3 with the oxides studied is found. Under the conditions of activation in air no decomposition of La 2 O 3 –CeO 2 solid solution is detected. The solution is, however, destroyed when the activation is carried out in the presence of acids.
