I wonder if you could give it to chemical plants or industrial forges that make use of it regularly. But the unknown sourcing, purity, and relatively tiny volume would probably be a total blocker - if not by company policy then by regulation. Maybe there's some kind of trial run or safety drill they can waste it on.
