GB/T 18882.2-2017 "Methods for chemical analysis of mixed rare earth oxides in ionic rare earth ores, Part 2: Determination of aluminum trioxide content" specifies two methods for the determination of aluminum trioxide content in mixed rare earth oxides of ionic rare earth ores: Inductance coupled plasma atomic emission spectroscopy (AES) method (ICP-OES) and Titrimetric method. The measurement range of Method 1 is 0.10% to 5.00%, and the measurement range of Method 2 is 4.00% to 15.00%. This standard is suitable for the accurate determination of aluminum trioxide content in rare earth oxides, providing a basis for the composition analysis and quality control of rare earth materials.
