Abstract

The ground amorphous powder was consolidated into a dense sintered body with a typical ultrafine $Al_2O_3-GdAlO_3$ eutectic structure by spark plasma sintering (SPS). Sintered material with ultrafine and dense eutectic structure was obtained by an appropriate combination of rapid quenching and SPS at lower temperature and more quickly than by conventional sintering. The $Al_2O_3$-based rare earth eutectic ceramics for solar cell emitters are believed to have a higher efficiency and the $Al_2O_3$ based eutectic ceramics with ultrafine grains will be one of the promising materials showing excellent selective emitter characteristics.
