Abstract
Mechanochemical synthesis of MgAl-layered double hydroxides (MgAl-LDH) with molar ratio MgAl = 3 was performed. The effect of the acceleration of milling bodies (500 and 1000 m s-2), activation time (5–90 min), and water addition on the phase composition of obtained samples, their structural parameters, as well as on the process of formation of mixed oxides, prepared after LDH calcination was studied. The conditions for the preparation of single-phase LDH were established. It was shown the possibility of the textural properties regulation of mixed oxides by change of the mechanochemical synthesis parameters of corresponding layered double hydroxides.
