Samarium Oxide SM2O3 powder


The chemical composition of Samarium Oxide

What is Sm2O3.

Samarium oxide

This powder is slightly yellowish white and comes in body-centered cubic (or monoclinic) two types of crystal systems. While rare earth oxides are similar in chemical properties to samarium, it is distinct from all other oxides because of its 1.45M*B magnetic moment.

Samarium oxide

The density

It is 8.347 g/cm3.

Samarium oxide

melting point

The number 2262 Samarium dioxide is insoluble when dissolved in water. However, it can be easily soluble in acid. Samarium dioxide absorbs water and carbon dioxide in the air. When exposed to moisture or dry conditions at higher than 150degC, Samarium Oxide forms readily on metallic samarium materials. The oxide layer peels off metal surfaces, much like the iron metal.

It is simple.

Samarium Oxide Sm2O3 Pulver


There are two ways to prepare Samarium oxide:

1. Thermal decomposition (III) of samarium

Sm2(CO3)3 – Sm2O3 + 3 CO2

2. To burn the metal in oxygen, or air, at a temperature of 150°C.

4Sm + 3O2 – 2Sm2O3


Samarium Oxide SM2O3 powder


Samarium dioxide can be used to add infrared light emitting glass and coatings in photosensitive materials, along with samarium permanent magnet material for drilling, metal samarium production, and so on.

Infrared absorption glasses that absorb infrared light are made with Samarium Oxide.

The control rods in nuclear power reactors use Samarium Oxide as neutron absorbers.

Samarium Oxide can be used to dehydrate and dehydrogenate primary and secondary alcohols

Samarium Oxide SM2O3 Powder Storage Conditions

Sm2O3 powder dispersion and usage performance will be affected by damp reunion. Samarium Oxide should therefore be vacuum packed and kept dry in a cool place. Sm2O3 should not be exposed to stress.

Samarium Oxide Sm2O3 powder packing and shipping

Many types of packing are available depending on the amount of samarium dioxide Sm2O3 powder.

Packing of Samarium oxide powder Sm2O3:

You can vacuum pack 100g, 500g, 1kg/bag or 25kg/barrel. Or as you request.

Powder shipping of Samarium oxide, Sm2O3

1) Shipments can be made by air or by sea. 2) Express shipping is possible as soon as payment receipt has been received.
