| Popis: | A YAlO3(hexagonal) solid solution with α=0.3678nm and c=1.046 nm crystallizes at 880° to 935°C from an amorphous material prepared in the molar ratio Y3+/Al3++=3:5 by a solution technique using hydrazine. The hexagonal YAIO3 phase transforms to Y3Al5O12(YAG) at 1005° to 1075°C. The YAG powder calcined at 1200°C can be densified to transparency in a vacuum for 2h at 1600°C without additives. |
