Synthesis of MgAl 2 O 4 spinel nanoparticles using a
This article reports a novel method to prepare MgAl 2 O 4 spinel nanoparticles. By calcining a powder mixture of bayerite and magnesium sulfate at 800 °C and washing with water single-phase MgAl 2 O 4 spinel nanoparticles were prepared. The powder mixture and the calcined products were characterized by differential thermal and thermogravimetric analysis (DSC-TG) X-ray diffraction (XRD Sintered magnesium aluminate spinel is made by using imported industrial alumina and high puritu caustic magnesia as starting materials through multi-stage homogenization process and sintered at ultra high temperature in shaft kiln.
