Production and typical specifications
-
Route: Carbonate precipitation from erbium solutions → filtration → drying; used as a water‑insoluble source convertible to the oxide by heating
-
Purity grades: Commonly listed at 99%, 99.9% (3N), 99.99% (4N), and 99.999% (5N) depending on supplier
-
Catalog context: Offered in multiple grades with SDS and data sheets for materials applications
Practical handling notes
-
Processing: For oxide, calcine the carbonate; for wet chemistry, treat with dilute acid to release CO₂ and form soluble erbium salts
-
Storage: Keep dry; follow SDS from supplier for PPE and handling
