Scope
This document describes the methods of determining the silicon content in nickel alloys by nitrogen monoxide flame atomic absorption spectrometry and molybdenum blue spectrophotometry. This document is suitable for determining the silicon content in nickel alloys. Method 1: The determination range (mass fraction) of nitrogen monoxide flame atomic absorption spectrometry is 0.2% to 1%; Method 2: The determination range (mass fraction) of molybdenum blue spectrophotometry is 0.050% to 4.20%.
