The excessive FeCl3 solution is added into the analytical sample.The metallic aluminiun (MAl) in the sample is made to oxidizing-reducing react with Fe3+ by means of stirring,resulting Al3+ coming into solution.The Al2O3 doesn't react,retains in the precipitate.After fluorine is removed and calcium,magnesium and iron separated from the Al3+ bearing filter liquor,the MAl content is determined with CuSO4 titrimetry,the MAl content is subtracted from the total Al content,then the Al2O3 content is calculated.
