Abstract
The influence of thermal or mechanochemical treatment on the structura l state of yttrium-aluminium garnet (YAG) is studied. The formation of tetragonal form of Y(3)AL(5)O(12) is assumed by X-ray diffractometry. The effects of the temperature, pressure and cooling rate are discuss ed and a scheme explaining the transformation is proposed. The thermal ly and mechanically activated samples show an increased reactivity tow ards some mineral acids.
