Chemical analysis of magnesite and dolomite refractory products (alternative to the X-ray fluorescence method) - Part 3: Flame atomic absorption spectrophotometry (FAAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) (ISO 10058-3...

This technical specification outlines the procedures for the chemical analysis of magnesium and dolomite refractory products, specifically addressing methods that do not utilize X-ray fluorescence. It details two principal analytical techniques: flame atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry. These methods are designed to determine the elemental composition of refractory materials with high precision and accuracy. The document establishes standardized protocols for sample preparation, reagent selection, instrument calibration, and data interpretation to ensure consistency across different laboratories. By adhering to these guidelines, laboratories can achieve reliable results when analyzing the chemical constituents of refractories used in high-temperature industrial applications. The scope covers the determination of various oxide and elemental components essential for quality control and product specification compliance within the refractory industry.
