Relationship between rare earth materials and magnet materials

- Nov 13, 2017 -

As a strategic resource in the 21st century, rare earth has become an important element in the field of new material development due to its unique chemical, optical, electrical and magnetic properties. It has been widely used in magnetic materials, petrochemicals, electronic communications, machinery, energy, Textile printing and dyeing, environmental protection, agriculture, metallurgy, steel, lighting, LED, glass, ceramics, instrumentation, automotive, aerospace, military and other fields.

  Our country is the world's magnetic NdFeB magnet manufacturing power. Over the years, magnetic materials have been playing an important role in exports in the electronics industry, and there have also been some trade surpluses of one of the products that have long been held. In the following years, China's market demand 500,000 tons of permanent ferrite, soft 200,000 tons, 50,000 tons of NdFeB magnets, accounting for about 50% of the global market.

   In the review of the rare earth magnets material has a long history, the development of some new materials, such as permanent magnets NdFeB magnets, magnetostrictive materials, magnetic refrigeration materials, magneto-optical storage materials, plays an irreplaceable role in the modern industry .
