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

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...

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...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
