"GB/T 18882.4-2024 Methods for chemical analysis of mixed rare earth oxides in ionic rare earth ores, Part 4: Determination of ferric oxide content by Inductance coupled plasma emission Light spectrum method" stipulates the determination method of ferric oxide content in mixed rare earth oxides of ionic rare earth ores. This standard adopts Inductance coupled plasma emission Light spectrum method (ICP-AES), which is suitable for the detection of ferric oxide content in rare earth oxides, carbonic acid salts, oxalates and other materials. The determination range is 0.010% to 1.80%. The method has the advantages of high Sensitivity, Good Precision and easy operation, which can provide scientific basis for quality control and trade of rare earth materials. The standard is under the supervision of the National Rare Earth Standardization Technical Committee and will be officially implemented on June 1, 2025.
