About Samarium Oxide Sm2O3 Powder:
Samarium oxide chemical formula is Sm2O3. Samarium oxide is a slightly yellowish-white powder, body-centered cubic or monoclinic two kinds of crystal system. Rare earth oxides have similar chemical properties, and samarium oxide is no exception, but its magnetic moment is 1.45M·B, different from other oxides. Samarium oxide density is 8.347 g/cm3. Samarium oxide melting point is 2262℃. Samarium oxide is insoluble in water but soluble in acid. Samarium oxide absorbs carbon dioxide and water in the air. Samarium oxide readily forms on metallic samarium surfaces under wet conditions or in dry air at temperatures greater than 150°C. Similar to the metal iron, this layer of oxide peels off the metal's surface, exposing more metal to continue the reaction.

How is Samarium Oxide Sm2O3 Powder Produced?
Samarium oxide may be prepared by two methods:
1. thermal decomposition of samarium(III) carbonate, hydroxide, nitrate, oxalate or sulfate:
Sm2(CO3)3 → Sm2O3 + 3 CO2
2. by burning the metal in air or oxygen at a temperature above 150 °C:
4Sm + 3O2 → 2Sm2O3
Applications of Samarium Oxide Sm2O3 Powder:
Samarium oxide can be used as an additive in infrared light-emitting glass, coating in photosensitive material, as well as samarium drilling permanent magnet material and metal samarium production, etc.
Samarium oxide is used in optical and infrared absorption glasses to absorb infrared radiation.
Samarium oxide is used as a neutron absorber in the control rods of nuclear power reactors.
Samarium oxide can catalyze dehydration and dehydrogenation of primary and secondary alcohols
Preparation of other samarium salts by samarium oxide.
Storage Condition of Samarium Oxide Sm2O3 Powder :
The damp reunion will affect Sm2O3 powder dispersion performance and using effects, therefore, samarium oxide should be sealed in vacuum packing and stored in a cool and dry room, the samarium oxide can not be exposure to air. In addition, the Sm2O3 powder should be avoided under stress.
Packing & Shipping of Samarium Oxide Sm2O3 Powder :
We have many different kinds of packing which depend on the samarium oxide Sm2O3 powder quantity.
Samarium oxide Sm2O3 powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Samarium oxide Sm2O3 powder shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
