Super Pure Rare Earth Oxides and Compounds to 99.9999%

Super pure Rare Earth oxides are obtained by Ion-exchange technology, it can reduce both Rare Earth impurities and non-Rare Earth impurities significantly, to purify individual Rare Earth oxides again to above 99.999% purity, some oxides can achieve 99.9999% purity. These super pure Rare Earth Oxides are widely used in making laser crystal, fibre coating, and high-tech ceramics.

The following are the available oxides and their reference analysis report, these oxides can also be made into different other compounds.

Processing capacity

For special applications, high purity Rare Earth oxides can be further processed into following compounds with the same level of high purity:

Acetate, Chloride, Carbonate, Nitrate, Oxalate
