Hydroxyapatite Nanopowders/Nanoparticle and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)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 Micron Powders
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/Nanoparticle is the main inorganic constituent of bone and teeth and therefore has been extensively studied as an artificial bone substitute. Moreover, composites prepared from synthetic hydroxyapatite and collagen have a great potential to mimic and replace skeletal bones. Biomedical applications of calcium phosphate based scaffolds take for example advantage of their ability to induce bone formation and vascularization and to cover varied uses such as bone augmentations, artificial bone grafts, maxillofacial reconstruction, spinal fusion, periodontal disease repairs and bone fillers after tumor surgery.

In fact, reconstructive tissue engineering is nowadays a highly active research area that involves the development of materials with outstanding properties. These can only be achieved by means of combining different components, processes and technologies. Scaffolds constituted by biodegradable polymers and hydroxyapatite nanopowder have a great potential due to the excellent combination of properties like enhancement of biocompatibility and reinforcing effect provided by the inorganic component and the facility of preparation. Researchers are nowadays extensively involved in the study of bionanocomposites based on hydroxyapatite nanoparticles/nanpowder due to both their recognized applications in the biomedical field and their high potential for new specific uses.

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...

Bismuth Oxide Sputtering Targets and Applications

Bismuth oxide with the chemical formula of Bi 2 O 3  is one the most important bismuth compounds. Bismuth oxide has been investigated extensively due to its optical and electrical properties such as large energy gap (from 2 to 4 eV), refractive index and high oxygen ion conductivity at high and medium temperatures. These properties make bismuth oxide one of the most perspective candidates for application in optoelectronics, solar cells and solid oxide fuel cells (SOFCs). Bismuth oxide has a few main polymorphic forms that are known as α, β, γ, δ. All polymorphs have different crystal structure and various optical, electrical and mechanical properties. Only two of them, the low temperature monoclinic α-phase and high temperature face-centered cubic δ-phase are stable. The other phases are metastable. Magnetron sputtering is a widespread method because of high deposition rate, dense and highly adhesive films, and possibility of using commercially available large area depositio...
