英文摘要	Rare earth elements doped yttrium aluminum garnet (YAG) transparent ceramics are technologically important laser host materials. Containerless solidification-controlled crystallization (CSCC) solution is a promising new technology for preparation of YAG transparent ceramic because of its advantages of simple process and mild condition. However, the mechanism of phase selection of YAG melt under containerless solidification condition is not clear. The containerless solidification of garnet Y3Al5O12 (YAG) was carried out using the aerodynamic levitation method at different cooling rates. The metastable YAlO3 perovskite (YAP) and subsequent YAP+Al2O3 eutectic were formed when the melts of YAG solidified at the cooling rates of 4 K/s. The samples contained both the metastable YAP/Al2O3 and stable YAG phase were obtained by increasing the cooling rate to 13 K/s. When the cooling rates increased to about 53 K/s, the YAG melts formed into monophasic YAG. At the cooling rate of about 250 Kis, the glass-ceramics was successively obtained without recalescence. The glass transition temperature T-g and crystallization temperature T-x were 880 degrees C and 910 degrees C respectively. XRD results indicate that the glass-ceramics contains metastable YAP and YAG.
