Sintering and microstructure evolution of Er1.5Y1.5-xScx+yAl5-yO12 garnet ceramics with scandium in dodecahedral and octahedral sites

The sintering behavior of scandium-containing garnet materials within the Y2O3-Er2O3-Sc2O3-Al2O3 system was investigated. Single-phase ceramic powders and optical ceramics’ samples of Er1.5Y1.5-xScxScyAl5-yO12 (x = 0.2 ÷ 1.5; y = 0.2 ÷ 0.8) were prepared. An increase of scandium content in the dodec...
