Global Gadolinium Oxide (Gd2O3) Suppliers, Manufacturers & Distributors Directory — Websites & Contacts
Discussion
I am building a public global directory of companies connected to gadolinium oxide (Gd2O3, CAS 12064-62-9).
This list focuses on companies for which I could verify a public product page, catalog entry, SDS/COA, company page, or supplier page. It is not possible to prove that any public web list contains literally every company in the world, so this should be treated as a verified working directory that can be expanded over time.
Last checked: 7 September 2026.
When contacting suppliers, buyers should normally ask for:
- Purity basis (for example Gd2O3/REO, TREO, trace-metals basis)
- TREO
- Individual rare-earth impurities
- Fe, Si, Ca, Al, Na, Cl and other non-rare-earth impurities
- Particle size / D10 / D50 / D90
- BET surface area if relevant
- LOI / moisture
- Crystal phase if relevant
- COA
- SDS
- Country of origin
- Packaging
- MOQ
- Lead time
- Incoterms
- Export documentation
