Scope
This method specifies the determination method for the content of aluminum oxide in mixed rare earth oxides from ionic rare earth ores. This method is suitable for the determination of the content of aluminum oxide in mixed rare earth oxides from ionic rare earth ores. The determination range (mass fraction): 0.030% to 2.00%.
