Heavy rare earth element-dysprosium
Dysprosium is white with low toxicity. The biological usage of dysprosium is still unknown. Just as other lanthanide elements-15 kinds of chemical elements with the atomic number from 57 to 71, are found in the monazite and bastnaesite, with a little bit existed in the xenotime and fergusonite. As the Rare Earth Investing News indicated, different from the light rare earth, the later development of the heavy rare earth, such as dysprosium is not uncertain after the cancellation of quota on export of China. Nevertheless, the heavy rare earth will still be short on the whole. 2. Application of dysprosium The royal Society of Chemistry held that the application fields of dysprosium were not as extensive as other rare earth elements. As a kind of pure metal, dysprosium can react with water and air. Therefore, it is very difficult to dispose. However, in recent years, due to the extensive application of dysprosium into neodymium magnetic materi...
