| Abstract: | After determination of iron,titanium was sheltered by adding bitter almond acid,Al 2O 3 content in the sample could be got by titrating aluminium using EDTA chelatometry. The results of the tests confirmed that the method of the determination of Al 2O 3 content in common refractory was practical, accurate and easy to operate. |
