Aluminium Oxide (Al2O3) Properties

Properties:
Alumina is a standout amongst the most cost effective and broadly utilized material in the group of engineering ceramics. The raw materials from which this ceramic is made are promptly accessible and sensibly estimated in price, bringing about great value for the cost in manufactured alumina shapes. With an incredible blend of properties and an alluring value, it is nothing unexpected that fine grain technical grade alumina has an extensive variety of utilizations. Aluminium Oxide (Al2O3) is hard and does not wear out easily. Aluminium Oxide (Al2O3) holds outstanding dielectric properties from DC to GHz frequencies. Al2O3 highly resists strong acid and alkali attack at high  temperatures .  Aluminium Oxide (Al2O3) has good thermal conductivity and acquires excellent size and shape capabilities. Al2O3 is strong and stiff. Al2O3 purity ranges from 94 percent, an easily metallizable composition, to 99.8 percent for the most demanding high temperature applications.
Aluminum oxide, regularly called alumina, has strong ionic interatomic bonding giving interest to its attractive material attributes. Aluminium Oxide (Al2O3) can exist in a few crystalline stages which all return to the most stable hexagonal alpha stage at high temperatures. This is the period specifically noteworthy for basic applications.
Alpha stage alumina is the strongest and stiffest of the oxide ceramics. Its hardness, superb dielectric properties, recalcitrance and great thermal properties make the material of choice for an extensive variety of uses. High purity alumina is usable in both oxidizing and reducing atmospheres to 1925°C.

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...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...
