FAQ - Technical & Supply Chain
-
Q:
Is Cobalt(II) Chloride Hexahydrate interchangeable with anhydrous Cobalt Chloride?
A: No. CAS 7791-13-1 identifies the hexahydrate, CoCl₂·6H₂O, while anhydrous cobalt chloride is CAS 7646-79-9. The hydrate changes formula weight, cobalt percentage, water balance and color. Specify the hydrate and assay basis before comparing offers. -
Q:
Which specifications should be agreed for Cobalt Chloride Hexahydrate?
A: Set cobalt assay and calculation basis, chloride, moisture or loss on drying, insoluble matter and application-relevant metals such as nickel, iron, copper, lead and zinc. Define particle form and dissolution behavior if a solution or catalyst feed is prepared. Review the batch COA against the approved grade.
