Dysprosium magnet is a rare-earth element and has a metallic, bright silver luster. It is quite soft and can be machined without sparking if overheating is avoided.
Dysprosium magnet’s physical characteristics can be greatly affected by even small amounts of impurities.
Dysprosium is never found in nature as a free element, though, like other lanthanides, it is found in various minerals, such as xenotime. Naturally occurring dysprosium is composed of seven isotopes, the most abundant of which is Dy
Dysprosium and holmium have the highest magnetic strengths of the elements, especially at low temperatures. Dysprosium magnet has a simple ferromagnetic ordering at temperatures below eighty five K .
Above eight five K , it turns into a helical antiferromagnetic state in which all of the atomic moments in a particular basal plane layer are parallel and oriented at a fixed angle to the moments of adjacent layers. This unusual antiferromagnetism transforms into a disordered (paramagnetic) state
Dysprosium Magnet has relatively few applications where it cannot be replaced by other chemical elements. It is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data-storage applications, and as a component of Terfenol-D (a magnetostrictive material). Soluble dysprosium salts are mildly toxic, while the insoluble salts are considered non-toxic.
The Global EV Dysprosium magnet market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Indian scientists fabricate rare Earth-free magnet that could reduce EV costs Rare-Earth elements are a constant in the automotive sector that are used to make permanent magnets that produce stronger magnetic fields.
Indian scientists have now fabricated an improved low-cost heavy rare earth-free magnet that could boost Electric Vehicle (EV) production in the country in near future.
Scientists from the Centre for Automotive Energy Materials at the International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) have designed improved rare earth Dysprosium magnet (Dy) , which is in high demand for Electric Vehicles and can make them more affordable. The details have been carefully noted.
