A novel synthetic route for magnesium aluminate (MgAl2O4
In this paper a novel and inexpensive route for the preparation of spinel magnesium aluminate (MgAl 2 O 4) is proposed. Magnesium aluminate photocatalyst was synthesized via sol- gel auto-combustion method using oxalic acid urea and citric acid fuels 350 C. Subsequently the burnt samples were calcined at different temperatures.
