Abstract

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.
