-Purity on Rare Earth Oxide Basis.
In the rare earth industry, chemical purities of rare earth oxides and compounds are often presented on a rare earth oxide basis (REO basis), i.e., the content of a specific rare earth oxide in comparison to total rare earth oxides (TREO) present: REO/TREO. The statement of “CeO2 > 99%”, often means CeO2/TREO > 99%. To obtain the absolute purity of a specific oxide, you can use the formula: REO/TREO X Percentage of TREO in the material.

Purity on Rare Earth Metal Basis.
In the rare earth industry, chemical purities of rare earth metals are often presented on a rare earth metal basis (REM basis)), i.e., the content of a specific rare earth metal in comparison to total rare earth metals (TREM) present: REM/TREM. The statement of “Ce > 99%” often means Ce/TREM > 99%. To obtain the absolute purity of a specific metal, you can use the formula: REM/TREM X Percentage of TREM in the material.
