FAQ - Technical & Supply Chain
-
Q:
Are Potassium Iodide and KI the same material?
A: Yes. Potassium iodide and KI identify CAS 7681-11-0. They are not potassium iodate, iodine or potassium bromide, which have different oxidation states and uses. Purchase documents should state anhydrous potassium iodide, assay basis and any grade-specific impurity limits. -
Q:
Which specifications should be agreed for industrial Potassium Iodide?
A: Specify KI assay and method, iodate or free-iodine limit, water or loss on drying, insoluble matter, chloride, sulfate, heavy metals and particle form where relevant. Packaging must protect the salt from moisture and contamination. Review the batch COA and SDS against the intended process.
