Beijing nonferrous metal research institute 15 provides news, said strong magnetic after ten years of scientific research, China has successfully developed the international advanced level of industrialization of high quality rare earth metal and alloy preparation technology, broke the technological monopoly of developed countries, for the development of China's strategic emerging industries to provide the material guarantee.

Rare earths, known as industrial "vitamins," are a collective name for 17 elements. Since the 1980s, with the rapid development of rare earth magnetism, catalysis and other materials, the global application of rare earth has increased significantly, and some countries even listed it as a "strategic element" in this century. Among them, high-performance rare earth functional materials have become the key support materials in strategic emerging fields such as automotive, electronics, IT, new energy, aerospace and so on.

Beijing nonferrous metal research institute predicts that in the next 10 years, rare earth functional materials with magnetic materials and new energy materials as the core will continue to be the focus of rare earth applications, as well as the strategic commanding point for the international cutting-edge technology field. Rare earth magnetic materials and new energy materials need high quality rare earth metals and alloys as basic raw materials.

China is recognized as the world's largest rare earth resources, rare earth reserves, ferrite minerals. After nearly 50 years of development, China has become the world's largest producer, consumer and exporter of rare earths. The output of rare earth smelting and separation products accounts for more than 90% of the world's total rare earth. But in the early 1990s, China's rare-earth metals industry was small in scale, backward in production technology and low in product purity.

Zhang shirong, a spokesman for the Beijing general institute of nonferrous metals research, said that in order to change China's backward production technology, equipment and low-grade products of rare earth metals and their alloys, and to break the technical blockade of foreign countries, China has made a series of important progress in strengthening research and development.

Zhang shirong said that through technological breakthroughs, China has improved the level of rare earth metal smelting and product grade. The purity of high purity rare earth metals in magnetic steel is ≥99.99%. China's rare earth neodymium iron boron magnets have entered the foreign monopoly of the high-tech field.

The Beijing nonferrous metal research institute where zhang shirong works is the largest comprehensive research and development institution in China's nonferrous metal industry. The institute's national engineering research center for rare earth materials provides technology that supports more than 65 percent of the world's production of rare earth products.
