Scope

This part of GB/T 18882 specifies the method for determining the amount of aluminum oxide in ionic rare earth ore mixed rare earth oxides. This part is applicable to the determination of the amount of aluminum oxide in ionic rare earth ore mixed rare earth oxides, and includes two methods: Method 1, inductively coupled plasma atomic emission spectrometry, and Method 2, titration. The determination range (mass fraction) of Method 1 is 0.10%~5.00%, and the determination range (mass fraction) of Method 2 is 4.00%~15.00%.
