Light Yellow Samarium Oxide Sm2o3 12060-58-1 For Magnets Ceramics And Electronics

Samarium Oxide (Sm₂O₃): Key Properties & Industrial Uses in Magnets, Ceramics and Electronics

Samarium oxide, chemical formula Sm₂O₃, is a metal oxide. It is insoluble in water but soluble in acids. Rare earth samarium oxide has extensive applications, especially in glass, ceramics, electronics and other fields where it plays important roles.

Applications

1. Raw material for samarium-cobalt permanent magnets and samarium metal production, also for memory components
2. Used in infrared absorbing glass
3. Coating material for photosensitive materials
4. Catalyst for industrial waste gas recovery and treatment
5. Additive for electronic components and ceramic capacitors

Production Method of Samarium Oxide
The main production method is oxalate precipitation: using samarium chloride or samarium nitrate solution as raw material, adjusting pH to 2 with oxalic acid, then precipitating samarium oxalate by adding ammonia water. After heating and aging, separation and washing, the product is dried at 110°C and finally calcined at 900-1000°C to obtain samarium oxide.
