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.

Rundown about Silicon Oxide Wafer

The main insulating material used in micro-technology is Silicon Dioxide, which in chemical symbols is written as SiO2. In semiconductor technology, SiO2 thin film layers are mainly used as dielectric material film in transistors, capacitors (DRAM) or flash-memories. Silicon Oxide Wafers are produced using crystallization, solid state and other ultra-high purification processes such as sublimation. This process forms a cylindrical ingot, which is then sliced and polished to form wafers. Thermal oxide is a kind of "grown" oxide layer, compared to CVD deposited oxide layer, it has a higher uniformity, and higher dielectric strength, it is an excellent dielectric layer as an insulator . In most silicon- based devices, thermal oxide layer play an important role to pacify the silicon surface to act as doping barriers and as surface dielectrics. The simplest way to produce an insulating silicon oxide layers (SiO2) on silicon wafers is to oxidize silicon with oxygen, which ...

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...
