| Abstract: | The barium aluminosilicate compound (BaAl2Si2O8 or BAS) has been synthesized by powder reactive sintering within a Spark Plasma Sintering (SPS) device. The reaction paths between the precursors (alumina, silica and barium carbonate powders) have been deeply investigated at different temperatures from 900° to 1550°C in order to get at the end, the hexacelcian crystallographic form without any undesirable other compounds. Thanks to this approach, a 3 step thermal treatment is proposed to get a fully dense and nearly pure (98 wt%) BAS. |
