Innovative Coating Method of MgAl2O4 or ZnAl2O4 on α-Al2O3 Spheric Nuclei

Innovative Coating Method of MgAl2O4 or ZnAl2O4 on α-Al2O3 Spheric Nuclei

Structured materials composed of α-Al2O3 spheres covered with a porous and thin layer of MgAl2O4 or ZnAl2O4 were obtained. The innovative coating method developed consists in the formation of a precursor gel of MgAl2O4 or ZnAl2O4 by citrate-nitrate combustion method. The alumina spheres are submerge...
