Facts about Europium Powder

*Europium is the least abundant of the rare earth elements. It is also the most reactive one. Europium is found in many minerals such as xenotime, monazite, bastnasite, and loparite. It is not found in nature as a free element.Europium was isolated in 1901 and is named after the continent of Europe.

*Europium is silvery metal that instantly oxidizes in air. It is the most reactive of the rare earth metals and ignites in air at temperatures in excess of 150 degree to 180 degree. Europium resembles calcium in its reaction with water. Also, Europium metal is the most reactive metal of all rare earth elements.

*Europium is about as hard as lead and is quite ductile.

*Europium is considered to be mildly toxic. Europium powder is considered to be a fire and explosion hazard.
*Europium is used in the printing of euro banknotes. It glows red under UV light, and forgeries can be detected by the lack of this red glow.



*Europium powder is used for low-energy light bulbs, thus europium powder gives a more natural light, by balancing the blue (cold) light with a little red (warm) light.
*Europium is excellent at absorbing neutrons, making it valuable in control rods for nuclear reactors.
*Europium-doped plastic has been used as a laser material. It is also used in making thin super-conducting alloys.

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...
