What is Evolution of crystalline aluminates from hybrid gel-derived precursors studied by XRD and multinuclear solid-state MAS NMR: II. Yttrium–aluminium garnet, Y3Al5O12 about?
The thermal evolution of structure in a hybrid gel of YAG composition (Y 3 Al 5 O 12 ) prepared from aluminum alkoxide and yttrium acetate was studied up to 12508C. XRD indicates that the gels are amorphous <9008C, when they abruptly crystallize to YAG and hexagonal YAlO 3 . The latter exists only brie ̄y, being fully converted to YAG by 10008C. 27 Al MAS NMR shows that after the loss of volatiles at 3758C, the Al occupies three types of sites in the amorphous gel (tetrahedral, octahedral and a site characterized by an NMR resonance at 38 ppm). The distribution of Al over these sites progressively changes during heating <9808C but 89 Y MAS NMR suggests that the Y is comparatively less mobile within the gel, achieving its ®nal YAG environment only after the YAG crystal structure has been established.
