FAQ - Technical & Supply Chain
-
Q:
Are Boric Acid and Orthoboric Acid the same substance?
A: Yes. Both names identify H3BO3, CAS 10043-35-3. It is not borax, sodium tetraborate or another borate salt. The complete identity and CAS number should be stated on purchase documents because boric acid and borate salts have different formula weights, alkalinity and use restrictions. -
Q:
Which specifications should be agreed for industrial Boric Acid?
A: Set assay and whether it is reported on an as-is or dried basis, water or loss on drying, chloride, sulfate, iron, heavy metals, insoluble matter and particle-size distribution. Food, compendial and industrial requirements differ, so the batch COA and regulatory documents must match the named grade and destination market.
