The new Nd-reduced, heat-resistant magnet developed at this time not only eliminates the use of terbium and dysprosium
, rare earths necessary for neodymium magnets that require high heat resistance, but it also reduces the amount of neodymium used.
The report then estimates 2016-2021 market development trends of Dysprosium
earth elements (HREEs), such as, dysprosium
, terbium, neodymium,
Japan plans to import 30 tonnes of dysprosium
from Kazakhstan this year, the daily said, adding that it plans to raise the shipment next year to more than 50 tonnes accounting for 10 percent of Japan s annual demand for the mineral.
hardens magnets against heat by reshaping their magnetic fields.
And some of these magnets also contain 3 to 10 percent of dysprosium
, which allows the magnets to reach higher temperatures and still maintain their strength.
, which are used for making LCD panels and hybrid vehicles, the
Among a variety of rare-earth elements, neodymium and dysprosium
are widely used as a magnetic material for motors in environmentally friendly vehicles and home appliances, while erbium is used as a dopant in optical fibers and cerium as an abrasive for polishing liquid crystal display (LCD) glass.
1) There was already ample Western concern about potential diminishing access to supplies of REEs, particularly after a 2009 draft report written by China's Ministry of Industry and Information Technology called for a total ban on foreign shipments of terbium, dysprosium
, ytterbium, thulium, and lutetium, and a restriction of neodymium, europium, cerium, and lanthanum exports.
They sound like superheroes from a Hollywood science-fiction movie: neodymium, promethium, dysprosium
The material under investigation was a single crystal of Dysprosium
The Asian behemoth now supplies approximately 95 percent of the world's consumption of "rare earths," such as cerium, neodymium, lathanum, yttrium, and dysprosium
