Tantalum Carbide Nanoparticles and Their Applications

Tantalum carbides form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaCx, where x usually varies between 0.4 and 1. Tantalum carbides are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity. They appear as brown-gray powders, which are usually processed by sintering.
TaC (Tantalum Carbide) Nanoparticles (99.5+%, 950 nm, Cubic) have high purity, small diameters, even distribution, large specific surface area, high surface activity and low apparent density, as well as the excellent mechanics, electricity and chemical properties. Tantalum carbide nanoparticles have higher hardness, melting point, wear resistance and low thermal expansion coefficient and high temperature elevated strength. Nanoparticles of tantalum carbides exhibit superior mechanical properties and their tailored particle size and shape is for improved sintering and densification.
Tantalum carbide nanoparticles are suitable to cut a variety of materials such as gray cast iron, ductile nodular iron, stainless steel, nickel-based alloys. Tantalum carbide nanoparticles coatings are used industrially for wear protection of steel moulds employed in injection cast molding of aluminum and aluminum alloys.
High speed steel tools for machining are coated with tantalum carbide nanoparticles and are used in high speed milling machine. Tantalum carbide nanoparticles are desirable for market applications such applications as boost rocket motor nozzles that require high thermal shock resistance. In the commercial sectors tantalum carbide nanoparticles have potential application as a material used for cutting tools and wear parts.
Tantalum carbide nanoparticles can be used in biomedical, corrosion, aerospace and electrotechnology applications. Tantalum carbide nanoparticles stand as a candidate material for next generation thermal heat protection, space aircrafts, automotive wear resistant liners, and propulsion-exposed components.
Due to their optical, electronic and magnetic properties tantalum carbide nanoparticles have been used for optical coatings, electronic contacts and diffusion barriers.

Usage of Silver Conductive Adhesive Paste in Corrosion Protection

In electronics, solders are main material to connect electrical components to substrates which are generally printed circuit boards. Although they are cheap, they are not effective if long term performance is considered since solders have low resistivity to corrosion relatively. Since corrosion reduce reliability, the cost of advanced technological systems such as RADAR, SONAR, LIDAR and more increase. In addition, small signals can be lost, and in huge data transfer, some of the data can be lost also especially which may lead catastrophic failures in critical systems. For instance, surface to air missiles can be launched to target which is not exist if the data coming from detection systems is noisy. Therefore, corrosion protection is necessary, and  silver conductive adhesive paste  is an essential candidate to replace PbSn solders due to its resistivity to corrosion. Silver conductive adhesive paste provide not only noisy reduction but also electromagnetic interference whi...

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...
