ActiveChemical analysis methods for determination of Fe2+ and Fe3+ in refractory products by the spectral photometric method with 1,10-phenanthroline
邻二氮杂菲分光光度法测定耐火材料中的二价和三价铁离子化学分析方法
Application Summary AI generated
This standard specifies a spectral photometric method using 1,10-phenanthroline to determine the concentrations of ferrous (Fe2+) and ferric (Fe3+) ions in refractory products. It is applied in the quality control and material analysis of ceramics, glass, and other high-temperature industrial materials, particularly for assessing iron oxidation states that affect product color, thermal stability, and performance. The method is used in laboratory testing environments within the refractory manufacturing and materials science industries.
