Low-Temperature Fabrication of Polycrystalline Yttrium Aluminum Garnet Powder via a Mechanochemical Solid Reaction of Nanocrystalline Yttria with Transition Alumina

Nanoindentation of melt-extracted amorphous YAG and YAG:Eu, Nd micrometric fibers synthesized by the citrate precursor method

“…The conventional solid state reaction method of powders 9 for the synthesis of YAG requires high temperatures (1600 • C) and a prolonged time of calcination. Several wet methods of synthesis have been developed [10][11][12][13][14][15][16] to diminish the crystallization temperature and increase the purity of the resulting YAG materials. The presence of intermediate phases such as metastable YAlO 3 , Y 4 A 2 O 9 and Y 2 O 3 has been observed in several synthesis methods.…”
