Abstract
Mixed-metal garnet (Y3Sc2Ga3O12, YSGG) samples were prepared by: (i) solgel,(ii) semi-sol-gel, and (iii) solid state reaction methods. In all cases, the precursor powders were calcined for 10 h at 800 oC in air, ground in an agate mortar and heated again for 10 h at different temperatures in the range of 1000–1400 oC 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 oC using the sol-gel technique and at 1200 oC using the semi-sol-gel route.
Abstract (in Czech)
Směsné granáty (Y3Sc2Ga3O12, YSGG) byly připraveny (i) solgel metodou,(ii) semi-sol-gel metodou a (iii) reakcí v pevné fázi. Prekurzory byly kalcinovány 10 h při 800 oC na vzduchu, rozemlety a znovu zahřívány 10 h při různých teplotách v rozmezí 1000–1400 oC. Připravené vzorky byly charakterizovány rtg. práškovou difrakční analýzou a SEM. Monofázový granát Y3Sc2Ga3O12 byl získán při 1000 oC sol-gel metodou a při 1200 oC semi-sol-gel metodou.
