Neodymium (Nd) is a rare earth metal. Light yellow, easily oxidized
in the air, used to make alloys and optical glass.
The advent of neodymium has activated the rare earth field, plays an important role in the rare earth field, and controls the rare earth market.
Uses of neodymium element: Used to make ceramics, bright purple glass, artificial rubies in lasers and special glass that can filter infrared rays. Used with praseodymium to make goggles for glass blowers. The Mich metal used in steelmaking also contains 18% neodymium.
Neodymium oxide Nd2 O3; molecular weight 336.40; lavender solid powder, easily damp, absorbing carbon dioxide in the air, insoluble in water, soluble in inorganic acids. The relative density is 7.24. The melting point is about 1900 ℃, heating in the air can partially generate neodymium high-valent oxide.
Uses: Used to prepare permanent magnet materials, colorants for glass, ceramics and laser materials. Adding 1.5% to 2.5% nanometer neodymium oxide to magnesium or aluminum alloy can improve the high temperature performance, air tightness and corrosion resistance of the alloy, and is widely used as aerospace materials. In addition, nano yttrium aluminum garnet doped with nano neodymium oxide produces a short-wave laser beam, which is widely used in the industry for welding and cutting thin materials with a thickness of less than 10 mm. In medical treatment, nano yttrium aluminum garnet laser doped with nano neodymium oxide is used instead of scalpel for surgical removal or disinfection of wounds. Nano neodymium oxide is also used for the coloring of glass and ceramic materials, as well as rubber products and additives.
Neodymium praseodymium metal; molecular formula: Pr-Nd; properties: silver-gray metal lumps, with metallic luster, easy to oxidize in the air. Uses: Mainly used as permanent magnet materials.
Neodymium is very irritating to the eyes and mucous membranes, and moderately irritating to the skin. Inhalation can also cause pulmonary embolism and liver damage.
Irritating to eyes, skin, mucous membranes and respiratory tract.
1. Inhalation: leave the scene to a place with fresh air. If breathing is difficult, give oxygen. Seek medical attention.
2. Eye contact: Lift the eyelid and rinse with running water or normal saline. Seek medical attention.
3. Skin contact: Take off contaminated clothing and rinse with running water.
4. Ingestion: Drink enough warm water to induce vomiting. Seek medical attention.
