Praseodymium Metal and Its Applications

Praseodymium(Pr) is the one of rare earth metals with atomic number 59. Praseodymium is a soft, silvery, malleable and ductile metal valued for its magnetic, electrical, chemical and optical properties. Due to praseodymium high potential reactiveness it is very hard to find a pure praseodymium metal in nature. It slowly develops a green oxide coating. Praseodymium was found by separating didymium into two different elements, which one of them was praseodymium and other was neodymium, in 1885 by the Austrian chemist Baron Carl Auer von Welsbach. The name praseodymium comes from the Greek prasinos meaning “green” and didymos “twin”. Praseodymium is stable only in aqueous solution with the 3+ oxidation state. Aqueous praseodymium ions are yellowish-green. Large amounts of praseodymium are found in monazite and bastnasite minerals. Praseodymium could be isolated by ion exchange and solvent extraction and through calcium reduction of anhydrous chloride or fluoride. The very first use of praseodymium was glass coloration yielding a yellow-green glass. The first enduring commercial use of purified is in the form of a yellow-orange stain for ceramics.
Praseodymium is used to create high-power magnets notable for their strength and durability
Praseodymium is used as an alloying agent with magnesium to create high strength metals that are used in aircrafts engines
Praseodymium fluoride forms the core of carbon arc lights, which are used in the motion picture industry for studio lighting and projector lights
Praseodymium is used to color ceramics yellow
Praseodymium as component of didymium glass is used to make certain types of welder’s and glass blower’s goggles
Praseodymium compounds give glasses and enamels yellow color
Praseodymium oxide is used as catalyst in solid solution with ceria or ceria-zirconia
Doping praseodymium in fluoride glasses allows it to be used as a single mode fiber optical amplifier
Flame lighters flints use misch metal containing praseodymium to produce sparks by friction
Praseodymium is used in nickel metal hydride rechargeable batteries for hybrid automobiles
Praseodymium is used in high-intensity permanent magnets, which are essential in electric motors and generators used in hybrid cars and wind turbines

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

Bismuth Oxide Sputtering Targets and Applications

Bismuth oxide with the chemical formula of Bi 2 O 3  is one the most important bismuth compounds. Bismuth oxide has been investigated extensively due to its optical and electrical properties such as large energy gap (from 2 to 4 eV), refractive index and high oxygen ion conductivity at high and medium temperatures. These properties make bismuth oxide one of the most perspective candidates for application in optoelectronics, solar cells and solid oxide fuel cells (SOFCs). Bismuth oxide has a few main polymorphic forms that are known as α, β, γ, δ. All polymorphs have different crystal structure and various optical, electrical and mechanical properties. Only two of them, the low temperature monoclinic α-phase and high temperature face-centered cubic δ-phase are stable. The other phases are metastable. Magnetron sputtering is a widespread method because of high deposition rate, dense and highly adhesive films, and possibility of using commercially available large area depositio...
