差示分光光度法测定硅铝铁合金中高硅李树伟，李凤丽（四川师范大学化学系成都，６１００６８）（成都航空发动机公司成都，６１００６６）关键词硅，合金，差示分光光度法硅铝铁合金在航空工业、机械工业领域有着广泛的应用。该合金中硅含量较高（硅含量１５－２０％），...
Determination of high-content Silicon in SiAeFe alloys by differential spectrophotometry isdiarribed. In HNO_3 medium (pH1～2), Si (Ⅳ) reacts with (NH_4)_2MoO_4 to form H_4[Si(Mo_3O_(10))_4]. Then it is reduced to molybdenum Blue by Fe (Ⅱ), the product being determined in therange of 7-l2% Silicon with 6% reference solution, 12-20% Silicon with 10%. It is showedthat this method had the advantage of simplicity, accuracy and being able to get satisfactory resultsin comparison with data of abtained by other authors.
