Resumen Información suministrada por el agente en SIGEVA
MgAl2O4 spinel was successfully synthesized using a mechanochemical route that avoided the formation and calculation of its precursors at high temperatures. The method involved a single step in which γ-Al2O3-MgO, AlO(OH)-MgO, and α-Al 2O3-MgO mixtures were milled at room temperature under air atmosphere. The formation of MgAl2O4 occurred faster with γ-Al2O3 than with AlO(OH) or α-Al 2O3. After 140 h, the mechanocbemlcal treatment of the γ-Al2O3-MgO mixture yielded ...
