A Rapid Determination of Micro-quantities of Silicon in Steels (II)

Hidehiro Gotô and Yachiyo Kakita


Abstract:

A colorimetric method with molybdenum blue for a rapid analysis of micro-quantities of silicon in steels was studied with Pulfrich's photometer. By the molybdenum blue method,using ferrous iron and oxalic acid as reducing reagent, silicon can be determined colorimetrically in the presence of iron. As little as 0.01% of silicon in steels is determinable by this method within about ten minutes.
