Abstract:
Conclusions
1. The mechanochemical activation of bayerite is accompanied by displacement of the hydroxyl units followed by splitting of the crystals into plates with thicknesses up to 10 å. During this displacement, the alternation of the units changes from ABAB... to ABBA..., which is characteristic of hydrargillite, and ABCABC..., which is characteristic of cubic packing.
2. The activation process is also accompanied by dehydroxylation with the formation of O2− and molecular water, which is located predominantly in the first coordination sphere of Al(III) cations; the transformation of bayerite into a compound which is amorphous to x-rays and has the formula Al2O3·3H2O, octahedral coordination of the Al(III) cations, and disordered cubic packing of OH−, O2−, and H2O.
