what's dysprosium ferrum(DyFe) alloy?

For preparing dysprosium metal, an additive to glass and Nd-Fe-B permanent magnets, also can be used in some aspects such as metal halogen lamp, magnetic memory material, Y-Fe or Y-Al garnet and nuclear industry.

Dysprosium (Dy) Metal Typical Applications

Dysprosium is used, in conjunction with vanadium and other elements, in making laser materials. Because of dysprosium's high thermal neutron absorption cross-section, dysprosium oxide-nickel cermets are used in neutron-absorbing control rods in nuclear reactors. Dysprosium-cadmium chalcogenides are sources of infrared radiation which is useful for studying chemical reactions. Because dysprosium and its compounds are highly susceptible to magnetization, they are employed in various data storage applications, such as in compact discs.

what's dysprosium metal?

Metallic dysprosium is bright silver in color and when combined tends to form greenish-yellow salts. Dysprosium is relatively stable in air at room temperature, yet tarnishes in moist air. The metal can be cut with a knife or machined without sparking (if care is taken to avoid overheating). Even small amounts of impurities can greatly affect dysprosium's properties

rare earth metal dysprosium

Dysprosium is most commonly used as in neodymium-iron-boron high strength permanent magnets. While it has one of the highest magnetic moments of any of the rare earths , this has not resulted in an ability to perform on its own as a practical alternative to neodymium compositions.

It is however now an essential additive in NdFeB production. It is also used in special ceramic compositions based on BaTiO formulations. Recent research has examined the use of dysprosium in dysprosium-iron-garnet (DyFeG) and silicon implanted with dysprosium and holmium to form donor centers.

Neodymium-iron-boron magnets can have up to 6% of the neodymium substituted with dysprosium to raise the coercivity for demanding applications such as drive motors for hybrid electric vehicles. This substitution would require up to 100 grams of dysprosium per hybrid car produced. Based on Toyota's projected 2 million units per year, the use of dysprosium in applications such as this would quickly exhaust the available supply of the metal. The dysprosium substitution may also be useful in other applications, as it improves the corrosion resistance of the magnets.

Dysprosium is one of the components of Terfenol-D, along with iron and terbium. Terfenol-D has the highest room-temperature magnetoresistance of any known material; this property is employed in transducers, wide-band mechanical resonators,and high-precision liquid fuel injectors.

Nanofibers of dysprosium oxide fluorideDysprosium is used in dosimeters for measuring ionizing radiation. Crystals of calcium sulfate or calcium fluoride are doped with dysprosium. When these crystals are exposed to radiation, the dysprosium atoms become excited and luminescent. The luminescence can be measured to determine the degree of exposure to which the dosimeter has been subjected.

Nanofibers of dysprosium compounds have high strength and large surface area; therefore, they can be used for reinforcement of other materials and as a catalyst. Fibers of dysprosium oxide fluoride can be produced by heating an aqueous solution of DyBr and NaF to 450 °C at 450 bar pressure for 17 hours. This material is remarkably robust, surviving over 100 hours in various aqueous solutions at temperatures exceeding 400 °C without re-dissolving or aggregating.
