Some applications of silicon carbide that are eye-catching

wallpapers News 2021-02-02
Silicon carbide can be used to produce graphene because its chemical properties can promote the epitaxial production of graphene on the surface of SiC nanostructures.
Emery prints
Silicon carbide is used in emery prints-a collagraph printmaking technique. Emery grains are applied to the surface of the aluminum plate in a paste form. When the paste dries, the ink is applied and captured in its granular surface, and then wiped away from the exposed areas of the printing plate. The ink plate is then printed onto paper on a roll press for gravure printing. The result is to print out the paint marks embossed on the paper.
 
Emery is also used in lithography. Its uniform particle size allows it to be used to "grind" a stone from which the previous image was removed. In a process similar to sanding, the coarser emery is applied to the stone and treated with Levigator, and then gradually finer and finer gravel is applied to the stone until it is clean. This creates a grease-sensitive surface.
Graphene production
In production, silicon is mainly used as a substrate for growing graphene. But there are actually several methods that can be used to grow graphene on silicon carbide. The constrained controlled sublimation (CCS) growth method consists of SiC chips, which are heated together with graphite under vacuum. Then release the vacuum very slowly to control the growth of graphene. This method can produce the highest quality graphene layer. However, other methods are reported to produce the same product.
 
When understanding how or when to use these graphene production methods, most methods mainly produce or grow this graphene on SiC in a growth environment. Due to the thermal properties of SiC, it is usually used at higher temperatures (for example, 1300°C). However, certain procedures have been implemented and studied, which may result in methods that use lower temperatures to help make graphene. More specifically, it has been observed that this different graphene growth method can produce graphene in a temperature environment of about 750°C. This method requires a combination of certain methods such as chemical vapor deposition (CVD) and surface segregation. When it comes to substrates, the process will include coating the SiC substrate with a transition metal film. After the rapid thermal treatment of the substance, carbon atoms will become more abundant at the surface interface of the transition metal film, thereby producing graphene. And it was found that this process produces a more continuous graphene layer on the entire substrate surface.
Quantum physics
Silicon carbide can form point defects in the crystal lattice. These defects are called color centers. These defects can generate single photons on demand, so they can be used as a platform for single-photon sources. This equipment is the basic resource for many emerging applications of quantum information science. If a person pumps a color center through an external light source or current, the color center will be excited and then relax with the emission of a photon.
Fishing rod guide
Silicon carbide is used to make fishing tackle because of its durability and wear resistance. The silicon carbide ring is installed in a guide frame usually made of stainless steel or titanium to prevent the pipeline from contacting the bar stock. The lifting ring provides a low-friction surface, which can improve the casting distance while providing sufficient hardness to prevent the braided fishing line from wearing.
