α型硅钼蓝法测铝中硅的研讨

A Study on the α-Silcon Molybdenum Blue Method for the Determination of Silicon in Aluminium

实验考察了影响硅钼蓝法结果重视性及准确性的因素;比较了α型硅钢蓝及β型硅钼蓝的异同、特点;提出了利用α型硅钼蓝法线性范围宽、稳定性好的优点,同时测定铸铝中高含量硅和铝合金中低含量硅的分析方法。

The factors effecting the accuracy of silicon molybdenum blue method were studied, the wand β-silicon molybdenum blue methods were compared. It was suggested to use the α-rmethod because of its wider linear range and better stability. an analytical method was established to determine the high alumininm content in casting aluminium and the low aluminium content in aluminium alloy.
