Rundown about Erbium Oxide

Erbium oxide (Er2O3) is the compound in the oxide form of the rare earth metal erbium. Erbium oxide is also known as erbia and erbium trioxide. Erbium oxide has a pink color. The cubic crystal structure is the structure that erbium oxide has. However, under certain conditions erbium oxide could have a hexagonal structure. Erbium oxide is not soluble in water, with a high melting point at temperature of 2344oC. Hence, this erbium oxide compound is said to be well heat endurable and chemically durable under high temperatures. Erbium oxide films have a high dielectric constant. At room temperature erbium oxide is strongly photo luminescent compound. Erbium oxide has been used in variety of applications like microelectronic, optoelectronic, thermophotovoltaic and biomedical applications. Erbium oxide is even used in nuclear reactors.
Erbium oxide is used as colorant for glasses
Erbium oxide is used as burnable poison for nuclear fuel
Erbium oxide is used in the protection of and anticorrosion coating of steels
Erbium oxide is used in the fabrication of high-gain optical waveguide amplifiers and optoelectronic integrated circuits
Erbium oxide is used for gate dielectrics of silicon-based microelectronic devices due to its high dielectric constant
Erbium oxide is used in solar cells as anti-reflection coating
Erbium oxide is used as insulating coating since it is effective in reducing magneto hydrodynamic pressure

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...
