摘要：

The influence of mechanical activation (MA) on gamma- and chi-Al2O3 is studied by means of X-ray phase analysis, The change of specific surface of aluminium oxides after MA is estimated, It is shown that the mechanical treatment leads to the change of the sequence of solid-phase transitions in aluminium oxide and a decrease of alpha-Al2O3 formation temperature.
