Scope

This Part of GB/T 18882 specifies the determination method of aluminum oxide content
in mixed rare earth oxide of ion-absorpted type rare earth ore.
This Part applies to the determination of aluminum oxide content in mixed rare earth
oxide of ion-absorpted type rare earth ore, including two methods: Method 1
Inductively coupled plasma atomic emission spectrometry and Method 2 Titration. The
determination range of Method 1 (mass fraction): 0.10% ~ 5.00%, and the
determination range of Method 2 (mass fraction): 4.00% ~ 15.00%.
