Frequently Asked Questions
What is the difference between amorphous and crystalline boron powder?
Amorphous boron is reactive and used in pyrotechnics and as a reducing agent. Crystalline boron is harder and less reactive, ideal for electronics and abrasives.
Is boron powder toxic?
Boron powder is generally low in toxicity but should be handled with care. Avoid inhalation and skin contact; use PPE.
What packaging options do you offer?
We provide sealed bags, drums, or custom packaging (e.g., vacuum-sealed) to prevent oxidation.
Can I request a sample?
Yes, we offer samples for quality verification.
What is the lead time for orders?
Standard orders ship within 3-5 days; bulk orders may take 1-2 weeks.
Do you supply boron powder for nuclear applications?
Yes, we provide high-purity boron (enriched in B-10 isotope) for nuclear use.
