Y4Al2O9 has been synthesized by means of the citrate-nitrate sol-gel combustion method using yttrium (III) nitrate and aluminium (III) nitrate. DTA/TG analysis, X-ray diffraction (XRD), FT-IR and 27Al magic angle spinning nuclear magnetic resonance (MAS NMR) measurements were used to characterize th...
