Abstract
A new method for the synthesis of high-purity fine-crystalline aluminum-magnesium spinel MgAl2O4 was been proposed. The procedure includes treatment of mixture finely dispersed MgO and hydroxide Al(OH)3 or aluminum oxyhydroxide AlOOH by water fluid under supercritical conditions (T = 380-400 °С, PH2O = 22,8-23,0 MPa). It was been shown that the process of formation of the structure of aluminum-magnesium spinel proceeds through a solid-phase mechanism. By varying the conditions of synthesis, the new method of synthesis allows to adjust the size (from 20 nm to 5 µm) and shape (spherical, lamellar, bipyramidal) of particles of synthesized aluminum-magnesium spinel MgAl2O4.
