YAG (Yttrium Aluminum Garnet) was successfully prepared through cathodic electrodeposition process by applying different current densities to the mixture of YCl3 and AlCl3 solution (water/ethanol 1:1 volume ratio). Hydroxide precursors were cathodically grown on the cathode surface (at different current densities) and then the obtained hydroxide powder was heat-treated at 1100 °C for 2 h. The oxide products were characterized by XRD, FTIR, DSC-TGA, SEM and EDAX techniques. The effect of applied current density on the morphology and particle size of YAG nanostructures were investigated through SEM images. Experimental results showed that the cathodic electrodeposition followed by heat-treatment can be used as a facile method for preparation of YAG nanostructures with different morphologies.
