Abstract
The phase changes of yttrium-aluminum garnet as a result of mechanoact ivation in a planetary ball mill have been studied. In addition to the structural changes the long term activation causes mechanolysis. The: latter provokes the formation of YAlO3, Al2O3 and Y2O3. The subsequen t treatment of activated samples with water and 18% HCl at 363 K leads to the conversion of similar or equal to 26% Of the garnet into a sol uble form. (C) 1998 Elsevier Science B.V.
