12 Things You Didn’t Know About Rare Earth Metals

12 Things You Didn’t Know About Rare Earth Metals 1 They’re Not That Rare. Most of the rare earth metals really aren’t that rare. Cerium (Ce) is the most abundant rare earth metal, followed by Lanthanum (La), and then Neodymium (Nd). Cerium, Lanthanum and Neodymium are all more abundant than Lead (Pb). 2 It’s actually [...]

  • Magnet Materials

Magnet Materials

Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]

How Neodymium Magnets are Made

How Neodymium Magnets are Made The method for manufacturing Neodymium Iron Boron magnets is as follows: MELTING OF THE ALLOY UNDER VACUUM The Neodymium metal element is initially separated from refined Rare Earth oxides in an electrolytic furnace. The Neodymium, Iron and Boron and the other chemical elements are weighted and put in a vacuum [...]

  • The Illegal Rare Earth Mining

The Illegal Rare Earth Mining in China

The illegal rare earth mining in China have resulted in skewed export numbers with further implications reaching to the loss of revenue, held down prices, and environmental concerns surrounding the small operations. In the face of this problem, the Chinese government has repeatedly vowed to shut down these illegal mining operations a task proving to [...]

  • The role of magnet powder in NdFeB

The role of magnet powder in NdFeB

The role of magnet powder in NdFeB Magnetic powder is an abbreviation for magnetic powder, and is an aggregate composed of a large amount of NdFeB basic material particles and interparticle voids. The powder body is a substance between a solid and a colloid. Solids below 0.1 μm are referred to as colloids, while solids [...]

  • Isotropic polymer bonded SmFeN magnets

Isotropic polymer bonded SmFeN magnets

Isotropic polymer bonded SmFeN magnets Sm-Fe-N magnet powders are produced in a similar way to Nd-Fe-B, except that nitrogen is introduced by heat treatment of rapidly quenched Sm-Fe flakes in a nitrogen atmosphere. These flakes are then mixed with a polymer binder and pressed or injected to make isotropic bonded magnets. Magnetic performance of (BH)max=112 [...]

  • Compression molded magnets

Compression molding magnets

Compression molding magnets Compression molded magnets are made by first mixing the magnetic powder with the polymer binder and then by compressing the mixture in a press mold. These magnets exhibit a higher level of performance than the injection molded couterparts due to higher density. Compression molded magnets   Features of compression molded [...]
