Samarium is a chemical element with the symbol Sm and atomic number 62.

Samarium is a silvery metal that belongs to the lanthanide series of the periodic table. It oxidizes slowly at room temperature and has a relatively stable oxidation state like europium.

Samarium is a medium-hard silvery metal that also has a wide variety of applications. For example, samarium cobalt magnets have high permanent magnetization and thermal stability. They are used in small motors, headphones, and musical instruments. Samarium compounds are used as efficient catalysts for different reactions, such as the decomposition of plastics and the dehydration of ethanol. Samarium 153 is used in cancer therapy, while Samarium 149 is a highly efficient neutron capture agent used in nuclear reactors.

Shaped Samarium Metal

We provide ingot, block, rod, and sputtering targets for shaped samarium metal. Foils and sheets are produced by the rolling process. Wherein praseodymium (Pr), samarium (Sm), and Lutetium (Lu) are difficult processes due to the crystal structure. They cannot be rolled, we’ll adjust the process according to user requirements. Thin products are not available for these elements.

Size range for each Samarium metal product:

Rod, Cylinder: 5-10mm diameter x 10mm length min

Round praseodymium sputtering target or disc:

Diameter: <18”, Thickness: >0.04”

Rectangular praseodymium sputtering target:

Length: <36”, Width: <12”, Thickness: >0.08”

Block & Ingot: Customized

Samarium Oxide

Samarium oxide is light yellow powder. It is insoluble in water.

Samarium(III) oxide (Sm2O3) is a chemical compound. Samarium oxide readily forms on the surface of samarium metal under humid conditions or at temperatures above 150°C in dry air. Similar to rust on metallic iron, this oxide layer flakes off the metal surface, exposing more metal to continue the reaction. The oxide is usually white to pale yellow in color and is often encountered as a very fine dusty powder.

Samarium Oxide Powder

We offer high-purity Sm2O3 in powders, granules, pellets, sputtering targets, and other custom forms.

Specifications of our Sm2O3

Sm2O3/TREO: 99.9% 3N, 99.99% 4N

Sm2O3 Powder, Granules, Pellets

Samarium Oxide Sputtering Target

Applications of Sm2O3

Sm2O3 can be used in optical and infrared absorbing glass to absorb infrared radiation. It can also be used as a neutron absorber in the control rods of nuclear power reactors, and as an oxide to catalyze the dehydration of acyclic primary alcohols to aldehydes and ketones.


Samarium (III) Fluoride

Samarium(III) trifluoride (SmF3), or samarium trifluoride, is a slightly hygroscopic crystalline ionic compound. Widely used as laboratory reagents, optical fiber doping, laser materials, fluorite luminescent materials, optical fibers, optical coating materials, electronic materials, etc.
