| Abstract: | The,, sample of steel slag iron powder by twice preparations would have homogeneous grain size and meet the requirements of chemical analysis. And the total iron content was determined by the titanium trichloride reduction and potassium dichromate volumetric method. The test results showed that the determination results of this method have good repetitiveness and are controlled in the range of national standard allowable errors. |
