Erbium Metal, Erbium foil Er purity 99.99% CAS 7440-52-0 For Additives Of Special Metallurgy

The metal erbium, as a member of rare earth elements, has unique physical and chemical properties. Its melting point is as high as 1529°C, showing excellent high temperature resistance and maintaining stable oxidation resistance at high temperatures. This property makes erbium metal widely used in aerospace, chemical and metallurgical fields. In the field of optical communication, erbium is the key material for producing erbium-doped fiber amplifiers, which can effectively enhance the transmission distance and efficiency of optical signals. In addition, erbium lasers play an important role in medical laser surgery, especially in eye surgery, because of their unique wavelength properties, enabling precise cutting and coagulation of tissue.
The metal erbium is also used in the preparation of magnetic materials to improve the magnetic properties of materials. Meanwhile, in the nuclear energy industry, erbium isotopes are also used as neutron sources for neutron detection and control of nuclear reactors.

Description

Erbium can be made into various forms: Erbium Foil, Erbium block, Erbium powder. Erbium is antiferromagnetic at low temperature, strong ferromagnetic at near absolute zero, and then superconductor. Erbium Metal can be prepared by reduction of anhydrous erbium fluoride with metallic calcium. In a vacuum induction furnace, a little excess of metal calcium chips or calcium particles are mixed with erbium fluoride, and then they are put into a tantalum crucible. Then they are put into a vacuum induction furnace to start vacuumizing and slowly heated to 400-600 ℃. After deep degassing, the purified argon is filled in, and the temperature rises to 800-1000 ℃, and the reduction reaction of the charge begins obviously. Then, the temperature is raised to 1500 ℃ and kept for 10-15 minutes, so that the metal and slag can be melted and separated from each other fully, so as to obtain a dense ingot, which is called metal Erbium.
