| Abstract: | Powder precursor in the form of hydroxyhydrogel was prepared from yttrium nitrate and aluminium nitrate, using ammonium hydroxide as precipitant by flash polycondensation technique. Precursor powder obtained in the hydroxyhydrogel form was characterized by TG/DTA, FTIR, SEM and XRD analysis. This method produced material which could be transformed into YAG at comparatively lower temperature (800 °C) and was phase pure. |
