What is neodymium oxide used for?
Uses. Neodymium(III) oxide is used to dope glass, including sunglasses, to make solid-state lasers, and to color glasses and enamels. Neodymium-doped glass turns purple due to the absorbance of yellow and green light, and is used in welding goggles.
Is neodymium oxide toxic?
Ingested neodymium salts are regarded as only slightly toxic if they are soluble and non toxic if they are insoluble. Neodymium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure.
Is neodymium oxide magnetic?
Physical properties Neodymium is paramagnetic at room temperature and becomes an antiferromagnet upon cooling to 20 K (−253.2 °C). In order to make the neodymium magnets it is alloyed with iron, which is a ferromagnet.
Is neodymium soluble in water?
Its electrical conductivity is about 240 S/m and heat capacity is ~100 J/(mol·K). NdCl3 is readily soluble in water and ethanol, but not in chloroform or ether. Reduction of NdCl3 with Nd metal at temperatures above 650 °C yields NdCl2: 2 NdCl3 + Nd → 3 NdCl.
Do neodymium magnets rust?
Neodymium magnets are like iron: without protection, they rust easily. To prevent corrosion, most neodymium magnets are plated with a three layer, nickel-copper-nickel plating. This particular plating combination has been the preferred corrosion protection for many years.
Are neodymium magnets radioactive?
Five of them are stable—neodymium-142 (27.13 percent), neodymium-146 (17.19 percent), neodymium-143 (12.18 percent), neodymium-145 (8.30 percent), and neodymium-148 (5.76 percent)—and two are radioactive, neodymium-144 (23.80 percent) and neodymium-150 (5.64 percent).
Does neodymium oxidize?
neodymium (Nd), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Neodymium is a ductile and malleable silvery white metal. It oxidizes readily in air to form an oxide, Nd2O3, which easily spalls, exposing the metal to further oxidation.
How many isotopes does neodymium have?
seven
Neodymium is a rare earth element (REE) that occurs in many silicate, phosphate, and carbonate minerals by substitution for major ions. It has seven stable isotopes.
Why is neodymium malleable?
Neodymium is a ductile and malleable silvery white metal. It oxidizes readily in air to form an oxide, Nd2O3, which easily spalls, exposing the metal to further oxidation….neodymium.

What is neodymium used for in everyday life?
Neodymium is also used in tanning beds because it lets the UV light pass through, but filters out the warm infrared light. When neodymium is incorporated into crystals in lasers, it forms a green light. These lasers are used in laser pointers, eye surgery, cosmetic surgery, and cancer treatments.
Are neodymium magnets safe?
Neodymium Magnet Safety. The neodymium magnets we sell are extremely strong. They must be handled with care to avoid personal injury or damage to the magnets. Neodymium magnets are more powerful than other kinds of magnets. The incredibly powerful force between magnets can often be surprising to those unfamiliar with their strength.
What is the melting point for neodymium?
Neodymium – Melting Point and Boiling Point. Melting point of Neodymium is 1016°C. Boiling point of Neodymium is 3127°C. Note that, these points are associated with the standard atmospheric pressure.
Where is Neodymium commonly found?
Neodymium is never found in nature as the free element. Neodymium is found in the ores monazite sand [(Ce, La, etc.)PO4] and bastn°site [(Ce, La, etc.)(CO3)F], ores containing small amounts of all the rare earth metals.
