Mechanochemisitry Synthesis of Al-Rich Layered Double Hydroxides

Article Preview

Abstract:

In present work mechanochemical synthesis of fine dispersed MgAl-CO3 LDHs is based on the preliminary mechanical activation of mixture of magnesium hydroxide, aluminium hydroxide and sodium hydrogen carbonate in a planetary activator AGO-2, followed by the thermal treatment of activation products at a temperature of 90 . The Mg/Al molar ratio was discussed. The samples were characterized by x-ray diffraction, thermogravimetry, scanning electron microscope, and energy dispersive spectrometer. According to obtained data the interaction mechanism was proposed.
