Silicon Carbide Beta Nanoparticles and Their Applications

Silicon carbide is an important non-oxide ceramic which has diverse industrial applications. Silicon carbide has exclusive properties such as high hardness and strength, chemical and thermal stability, high melting point, oxidation resistance, high erosion resistance, etc. All of these qualities make silicon carbide a perfect candidate for high power, high temperature electronic devices as well as abrasion and cutting applications.
As mentioned above silicon carbide is a promising ceramic for various industrial applications thanks to its excellent properties. Silicon carbide is a binary compound semiconductor consisting of carbon and silicon, where each atom is sp3 -hybridized and forms four bonds to four other atoms of the opposite kind. On the other hand, the crystal structure gives rise to polytypism, which is a one-dimensional polymorphism. Unlike most other semiconductors, which only occur in one or two different crystal structures each, silicon carbide exists in over 250 known polytypes. The difference among the polytypes is the stacking sequence along the с-axis of the lattice. The cubic polytype is referred to as β-SiC, whereas the hexagonal and rhombohedral structures are referred to as α-SiC.
Due to the low stacking-fault energy, it is easy to form different silicon carbide polytypes, making it possible to obtain silicon carbide crystals with different properties for various applications. Properties and applications silicon carbide has been widely studied for various applications because of its high Young’s modulus and hardness, excellent oxidation and corrosion durability, high strength at elevated temperatures, and good thermal shock resistance. Moreover, silicon carbide is a promising semiconducting material for application in areas of high temperature, high power, high frequency and harsh environments.
As we mentioned cubic polytype of silicon carbide is named as beta-silicon carbid which is shown as β-SiC. Beta silicon carbide nanoparticles can be used various applications. For example since SiC (Silicon Carbide) Beta Nanoparticles (99.5+% , 790 nm ) can be used in sintered ceramic parts and in abrasive applications such as high performance brake parts.

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...

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...

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 ...
