GB/T 18882.2-2017 Chemical analysis methods for mixed rare earth oxideof ion-absorpted type rare earth ore—Part 2:Determination of aluminum oxide content
Abstract
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%.
