Sol-gel synthesis of yttrium aluminum garnet (YAG): effects of the precursor nature and concentration on the crystallization

2018 
Poly-cationic syntheses lead generally to polyphazed samples in Al2O3-Y2O3 diagram. Cross-reactivity of Al- and Y-precursors can be adjusted with an Al-alkoxide and an yttrium salt. YAG can successfully be synthetized by sol gel method from aluminum alkoxide and yttrium salt. Crystallite size increases significantly with precursor concentration.
