Application of silicon carbide nanomaterials

High thermal conductivity of Silicon carbide nanomaterials has many outstanding characteristics. The wide range of applications for electronic and optoelectronic devices made out silicon carbide single crystals is extensive. They can be used in special environments like aerospace, radio communications, cars, oil drilling, high-temperature radiation, as well as automobiles. The unique optical and electrical properties of silicon carbide single crystals are also very useful in many other fields.
1. Its application in composite materials and the mechanical properties of nanosilicon carbide
Silicon carbide whiskers possess excellent qualities such as high strength, hardness, elastic modulus and lightweight. This material is widely used in many industries, such as aerospace, chemical and chemical industry, automobiles, and ships. The “King of Whiskers”, for good applications, is also known. Researchers have measured and calculated the mechanical properties in microscopic fields of one single whisker. Study results have demonstrated that the strength of silicon carbide linear is superior to that of bulk silicon caride ceramics in terms of tensile or bending. The carbide silicon nanowires have wide application potential and can be used in composite material reinforcements.
The propellers on helicopters can be strengthened to make them more resistant to air.
2. Carrier for nanosilicon carbide or catalyst
High specific surface areas have always been a key property of catalyst carriers that should be studied. Because of its excellent performance, silicon carbide’s high specific surface area is more efficient than any other catalyst carriers. SiC material outperforms traditional carriers such as silicon oxide or silica. The advantages of SiC material are mainly due to the following: 1) High thermal conductivity and strong resistance to heat; 2) high chemical stability; (3) high mechanical strength; Not easy for break; 4) Low thermal expansion rate.
3. The field emission properties of nanosilicon carbide
SiC’s nanowire array features a low threshold voltage and turn-on potential, high current density, field emission performance and stable field emission. It is an excellent field emission cathode material. The stable chemical properties of SiC nanowire array, as well as high temperatures and high pressure resistance, corrosion resistant, and other properties makes it a popular choice in the field microelectronics devices.
4. Optoelectronic properties for nano silicon carbide
Another luminescent material that was discovered is silicon carbide. In a low-temperature environment, silicon carbide can emit blue light. The wide bandgap characteristic of silicon carbide is used to create blue-like light emitting diodes. Its indirect bandgap properties make it very difficult to produce blue-like light emitting diodes. Also, the stability of silicon carbide is poor. The luminous efficiency of this material is low and limits its applications. Numerous improvements have been made in order to increase the luminous efficiency and availability of silicon carbide, such as the production of amorphous silicon, single-crystal porous silicon, or porous silicone carbide.
