Abstract
Pure gadolinium gallium garnet (Gd 3Ga 5O 12, GGG) powders had been synthesized from a mixed solution of Gd and Ga nitrates with stoichiometric mole ratio of 3:5 (Gd/Ga) via co-precipitation using ammonium hydrogen carbonate (NH 4HCO 3, AHC) as the precipitant. XRD, TEM, and thermal analysis were used to characterize the phase evolution and morphology of the final powders. The synthesized GGG polycrystalline materials were loosely agglomerated and showed good dispersity and excellent sinterability.
