Properties, Uses and Interesting Facts About Praseodymium



Photographes retrieved from http://www.angrysquirrelstudio.com/praseodymium-the-classic-periodic-table-illustrated/
- Praseodymium is a chemical element with symbol Pr and atomic number 59.
- Praseodymium is a soft, silvery, malleable and ductile metal in the lanthanide group.
- Praseodymium is valued for its magnetic, electrical, chemical, and optical properties.
- Praseodymium reacts slowly with oxygen: when exposed to air it forms a green oxide that does not protect it from further oxidation.
- Praseodymium is more resistant to corrosion in air the other rare metals, but it still needs to be stored under oil or coated with plastic.
- Praseodymium reacts rapidly with water.
- A major use of Praseodymium is in a pyrophoric alloy used in cigarettes lighter flints.
- Praseodymium is used in a variety of alloys.
- Praseodymium oxide is used in carbon electrodes for arc lighting, and it is know for its ability to give glass a nice yellow colour.
- Salts of praseodymium are used to color glasses and enamels; when mixed with certain other materials, praseodymium produces an intense and unusually clean yellow color in glass. Didymium glass, of which praseodymium is a component, is a colorant for welders goggles.
- Praseodymium can be used as alloying agent with magnesium to create high strenght metals that are used in aircraft engines
- Praseodymium is used in carbon arc electrodes for studio lighting and projection.
- Praseodymium is also used in alloys for permanent magnets.
- Praseodymium is one of the rare chemicals, that can be found in houses in equipment such as colour televisions, fluorescent lamps, energy-saving lamps and glasses.
- Praseodymium is one of the more abundant of rare-earth elements. It is four time more abundant than tin
- Praseodymium is considered to be moderately toxic.

Graphene Tyres and Graphene Brake Pads

Could Graphene Use Create A Distruptive Technology In Tyre Sector? Almost every day, we see new applications emerging from graphene. The fact is certain; graphene is a disruptive technology that holds huge potential for commercialization. Graphene has abilities to open new markets and even replace existing materials or material technologies. A brand new application of graphene came out which is producing graphene tyres and brake pads. https://www.canadacarbon.com/brake-linings-gasket... In 2016 GraphChina (Graphene Innovation Conference); Sentury and Huagao launched their first electrostatic conducting graphene tyre on September 22nd. 2-3 weeks before the conference Sentury and Huagao officially announced their cooperation on the product. During the press conference, Sentury’s engineers (which is branded with the Landsail moniker), revealed that the latest test data shows their graphene-enhanced tyre offers; 1.8 meters shorter stopping distances (6 % improvement on conv...

Characterization and potential uses of Hydroxyapatite Nanopowder/Nanoparticle

   Hydroxylapatite , also referred to as hydroxyapatite (HA), is a calcium apatite in its naturally occurring mineral form with the formula Ca5(PO4)3(OH). A fluorapatite or chlorapatite may be produced if the OH−ion is replaced by fluoride, chloride or carbonate. Hydroxylapatite crystallizes in the hexagonal crystal pattern. Pure hydroxylapatite powder is of white color. However, naturally occurring apatites can also have brown, yellow, or green hue, resembling the coloration of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticle (HApN) , nanodots or nanocrystals are spherical or faceted high surface area oxide magnetic nanostructured particles. Nanoscale Hydroxyapatite Nanopowder/Nanoparticle (HApN) are normally 20-80 nanometers (nm) with specific surface area (SSA) in the 15 - 50 m2/g range but sometimes available with an average particle size of 100 nm range with a specific surface area of approximately 5 - 10 m2/g. Hydroxyapatite Nanopowder/Nanoparticle (HApN...
