Silicon carbide is a nanomaterial that has many outstanding properties. These include high thermal conductivity; strong thermal stability; oxidation resistance and chemical corrosion resistance. It also has a low thermal expansion factor, high thermal and electrical conductivity at critical break-down conditions, and a small dielectric constant. Silicon carbide single-crystal devices are widely applicable in high-temperature environments, such as those found in aerospace, radar communications and automobiles. Its optical, electrical and mechanical properties, as well as its uniqueness, have a wide range of potential applications. 1. The mechanical properties and application of nanosilicon carbide composite materials

The whiskers made of silicon carbide are highly resistant to heat and corrosion and also have excellent chemical properties. It is used widely in the chemical, aerospace, automobile, and ship industries. It is also called “King of Whiskers”. Scientists are able to calculate and measure the mechanical properties of one whisker at a microscopic level. Studies have shown the linear silicon-carbide ceramics are superior to bulk silicon-carbide ceramics in terms of tensile and bend strength. The carbide silicon nanowires have excellent performance and can be used to reinforce high molecular materials such as ceramics, metals, and polymers.

The use of silicon carbide in ceramic composite materials improves the heat resistance of the ceramics as well as their original brittleness.

2. Nano silicon carbide as a catalyst carrier

It has always been important to examine the high specific surface areas of the carrier catalyst. High specific surface area silicon carbide has a better performance when used as a carrier for catalysts due to its excellent material performance. Comparing SiC to traditional carriers alumina, silica oxide, etc. the SiC material’s superiority is mainly shown in the following: 1) high heat resistance and thermal conductivity; 2) high chemical stability; 3) strong mechanical strength; not easily broken; 4) low rate of thermal expansion.

3. Field emission properties nano-silicon carbide

SiC Nanowire Array has a stable field emission performance and a low threshold voltage. This makes it an ideal cathode for field emission. It is widely used for microelectronics due to its chemical stability, high temperature, high pressure, and corrosion resistance.

4. Nano-Silicium Carbide: Optoelectronic Properties

The luminescent properties of silicon carbide were also discovered earlier. In a low-temperature environment, silicon carbide can emit blue light. Silicon carbide’s wide bandgap is used by people to make light emitting diodes that look blue. The low luminous efficiency and weak blue light of silicon carbide are due to the indirect bandgap properties. In order to increase the luminous efficacy of silicon carbide, several improvements have taken place, such as the production of amorphous silica carbide, single-crystal porous silicon carbonate, and porous silica carbide.
