Cerium Metal Applications

Cerium(Ce) is the one of rare earth metals with atomic number 58. Cerium is a malleable, soft, ductile, iron-grey metal, slightly harder than lead. The commercial-grade cerium is iron-gray in color. Cerium is very reactive element that readily tarnishes in air, slowly oxidizes in cold water and rapidly in hot water. It could be burned when heated or scratched with a knife. Cerium dissolves in acids. Cerium was first found by Jöns Jacob Berzelius and Wilhelm Hisinger in Sweden in 1803, and independently by Martin Heinrich Klaproth in Germany. However, cerium was isolated in 1839 by Carl Gustav Mosander. Cerium was named for the asteroid Ceres, which was discovered in 1801. Cerium is found in many minerals, but the main sources of cerium are monazite and bastnasite. The pure cerium is prepared metallothermic technique reducing cerium fluoride by calcium, or using electrolysis of molten cerium chloride. Cerium is interesting due to its variable electric structure. Cerium is the most abundant of all lanthanides making up 66 ppm of Earth’s crust. Cerium compounds have a number of practical applications. The first usage of cerium was in gas mantles. Nowadays, cerium use is still growing because of fact it is suited to produce catalyzers and to polish the gas.
Cerium is the major component of mischmetal alloy (just under 50%) which used in “flints” for cigarettes lighters. This is because cerium will make sparks when struck.
Cerium is used in aluminum and iron alloys, stainless steel as a precipitation hardening agent to make permanent magnets.
Cerium oxide is used as catalyst which is applied inside of walls of self-cleaning ovens to prevent build-up of cooking residues.
Cerium oxide catalyst is used as catalytic converters to clean up exhaust vehicles, it also catalyzes the reduction of nitrogen oxides nitrogen gas.
Cerium sulfide is used as pigment. This pigment is a non-toxic compound that is red rich color.
Cerium is also used in flat screen TVs, low energy light bulbs and flood lights.

Carbon Nanotubes Specifications and Properties Carbon Nanotubes, simply CNTs, are allotropes of carbon with a round and hollow nanostructure. These barrel shaped carbon molecules have crucial properties, which are significant for nanotechnology, hardware, optics and other different fields of materials science and innovation. The carbon nanotube’s excellent quality as a strong and firm material laid the basis on many applications. Not to mention carbon nanotubes exceptional heat conductivity, electrical and mechanical properties, Carbon Nanotubes are used as additives to diverse auxiliary materials. In terms of rigidity and flexibility Carbon Nanotubes are the stiffest and strongest materials. These quality outcomes from the covalent sp2 bonds framed between the individual carbon molecules. Unlike Graphene , Carbon Nanotubes are either conductive or semiconducting along the tubular hub. Carbon Nanotubes also have absorption, fluorescence properties. Bulk Carbon nanotubes are util...

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...
