, hematite, silica and calcium oxide in alumina crucible, heating in argon to 1380℃ and holding at this temperature for 1h. The crucible was taken out of furnace and the molten slag was immediately poured...) quenching specimen: the molten slag was rapidly cooled down by water so as to know the in-situ phase status and compositions. The main furnace used in this study was a vertical tube furnace......
