is dysprosium a metal

The addition of between 3 to 6 percent dysprosium (by weight) to the NdFeB magnetic alloy increases the magnet's Curie point and coercivity, thereby, improving stability and performance at high temperatures while also reducing demagnetization. This is due to the fact that pure dysprosium is strongly paramagnetic above -93°C (-136°F), meaning it is attracted to magnetic fields within a wide range of temperatures.

It is the best material for capturing hot neutrons, which has some applications in controlling nuclear processes. As a result, dysprosium and other heavy rare metals are often mo… Nature's Building Blocks: An A-Z Guide to the Elements.Oxford University Press; New Edition edition (Sept. 14 2011)Arnold Magnetic Technologies. Now the metal costs only about $300/ kg in purities of over 99%. Research by General Motors and Sumitomo Special Metals led to the creation of these stronger, cheaper versions of the first permanent (samarium-cobalt) magnets, which had been developed 20 years earlier. It is really just a nonmetal. Backed by profound experience of our experts, we are an unparalleled name engaged in providing the high-quality assortment of Dysprosium Metal. Dysprosium metal is not widely used so far. The metal can be cut with a knife or machined without sparking (if care is taken to avoid overheating). Presentation: September 24, 2013. Dysprosium turnings ignite easily and burn white-hot. The Ames Laboratory, along with the Naval Ordnance Laboratory, was also central in developing one of the first major uses for dysprosium, Terfenol-D. It is a pastel yellowish-greenish, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers and dysprosium metal halide lamps. Like the other metals in the rare earths group, dysprosium is usually separated from its kin via time consuming processes that drive up the cost of getting the isolated element. Global production of dysprosium is limited to about 1800 metric tonnes (contained dysprosium) annually. This, in turn, led to rapidly increasing prices and significant investment in the development of alternative sources. It is relatively stable in air at room temperature, but dissolves readily, with the evolution of hydrogen, in mineral acids. Carbon is a nonmetal but can sometimes be classified as a metalloid. Dysprosium's high melting temperature and neutron absorption cross section also allow it to be used in nuclear control rods. It is quite stable in air, remaining shiny at room temperature. January 17, 2012.British Geological Survey. Dysprosium ingot, 99.9% trace rare earth metals basis CAS Number 7429-91-6. As the Investing News Network has previously discussed, deposits rich in heavy rare earths like dysprosium are less common than deposits rich in light rare earths. Boisbaudran also discovered gallium in 1875 and isolated samariumfor the first time in 1879 using fractional separation. Dysprosium is a silver rare earth metal with atomic number 66 and element symbol Dy. Dysprosium is a metal. Cost. Dysprosium metal assay – 99.53% Metallisation of ferro-dysprosium and zirconium progressing ASM, through its partner Ziron Technology Corporation (Ziron Tech), has successfully produced 7.5 kg of a high purity dysprosium metal at its commercial pilot plant in South Korea. Dysprosium metal shiny sample of 1 gram 99,95% in glass vial The naturally occurring isotopes are all stable and have mass numbers 164 (natural abundance 28.3 percent), 162 (25.5 percent), 163 (24.9 percent), 161 (18.9 percent), 160 (2.33 percent), 158 (0.10 percent), and 156 (0.06 percent). He named the new element after the Greek word dysprositos, meaning 'hard to get'. The name Dysprosium comes from the Greek word (dysprositos), which means “difficult to get at”. Dysprosium metal is a bright silvery, very soft, and malleable rare earth metal that remains relatively stable in air at room temperature. Low in toxicity, the metal has no known biological role. Metallic dysprosium is bright silver in color and when combined tends to form greenish-yellow salts. The metal slowly reacts with water and quickly dissolves in diluted acids—except hydrofluoric acid (HF), in which it forms a protective layer of insoluble DyF3. Dysprosium is a rare earth element with bright silver, metallic color. The metal is further purified by vacuum distillation. Stanford Advanced Materials supplies high-purity dysprosium metal and dysprosium metal powder. Dysprosium metal is used in rare earth magnet alloys and magnesium alloys. The β-phase has a = 3.595 Å, b = 6.184 Å, and c = 5.678 Å at 86 K (−187 °C, or −305 °F). Dysprosium metal reacts with all the halogens to form dysprosium(III) halides. The magnetostrictive material was researched during the 1970s and commercialized in the 1980s for use in naval sonars, magneto-mechanical sensors, actuators, and transducers.
