- Abstract
Mixed-metal garnet (Y3Sc2Ga3O12, YSGG) samples were prepared by: (i) sol-gel, (ii) semi-sol-gel, and (iii) solid state reaction methods. In all the cases, precursor powders were calcined for 10 h at 800 °C in air, ground in an agate mortar and heated again for 10 h at different temperatures in the range of 1000-1400 °C in air atmosphere. The synthesized samples were characterized by X-ray powder diffraction analysis and scanning electron microscopy. It was demonstrated that monophasic Y3Sc2Ga3O12 garnet could be obtained at 1000 °C using the sol-gel technique and at 1200 °C using the semi-sol-gel route.
