Silicon Carbide

 

Advantages of Silicon Carbide

Excellent high-temperature performance
The melting point of silicon carbide products is as high as 2700°C, which can maintain its structural stability and strength in high-temperature environments, so it is widely used in high-temperature molten metals, high-temperature heating furnaces, high-temperature petrochemical and other fields.

 

Strong corrosion resistance
Silicon carbide has excellent corrosion resistance and can work stably for a long time in acid, alkali and oxidative environments.

 

High hardness and high strength
Silicon carbide has higher hardness and strength than traditional ceramic materials, so it has good wear resistance and impact resistance.

 

Excellent thermal conductivity and electrical conductivity
Silicon carbide has high thermal conductivity and excellent electrical conductivity, so it is widely used in the manufacture of high-power electronic components and radiators.

Application of silicon carbide

Electronics and Semiconductors:
In the electronics and semiconductor industry, silicon carbide is gradually becoming a preferred alternative to traditional silicon. Its high thermal conductivity and high voltage resistance make it an ideal material for manufacturing electronic components that operate at high power, high frequency, and high temperatures. From power amplifiers to RF switches, silicon carbide helps enhance the efficiency and performance of electronic devices.

Abrasives and Cutting Tools

Silicon carbide’s hardness and durability make it an excellent abrasive material, widely used in grinding wheels, sandpapers, and cutting tools. It is particularly effective for cutting and grinding hard materials like stone, glass, and metal.

Electric vehicle industry

Used in power modules and inverters for electric motors. Silicon carbide can operate in high-temperature, high-voltage, and high-frequency environments, improving EV efficiency and reducing energy loss.

Energy Industry

In the energy sector, silicon carbide is used in advanced applications such as gas turbine engines, nuclear energy, and solar power. Its high-temperature stability and chemical inertness enable it to withstand corrosion and thermal stress under extreme conditions, improving energy conversion efficiency.

Ceramic Products

The high hardness and wear resistance of silicon carbide make it highly promising for manufacturing ceramic tools, abrasives, and ceramic bearings. These application areas require materials with excellent wear resistance and corrosion resistance.

Coating Technology

Silicon carbide coatings can provide wear-resistant and corrosion-resistant surface protection, applicable in aerospace, automotive, chemical, and other fields. These coatings protect the substrate material from external environmental and physical damage.

LED Industry

The first set of light-emitting diodes to be produced made use of silicon carbide technology. It was used to manufacture blue, red, and yellow LEDs. LEDs are used in televisions, display boards, and computers.

 

Silicon carbide production method

 

Acheson Process

Feedstock: The feedstock consists of SiO2 in the form of silica or quartz sand and carbon in the form of powdered coke.
Mixing: The first step is to mix silicon dioxide and carbon in an electric resistance furnace. A graphite rod stands in the center, while other substances surround the core.
Heating: Then, a current is passed through the graphite rods to heat it to high temperatures of about 2200°C.
Finally, a layer of silicon carbide is formed around the rod, and CO emits.

Reaction Bonded SiC (RBSC)

Mixing: Combine coarse silicon carbide, silicon, and plasticizers together.
Machining: Form the blending into a desirable shape.
Heating: Expose these pieces to liquid or vapor silicon at high temperatures, and set them for further polishing.

Modified Lely Process

Based on the Acheson process, the Lely method synthesizes bulk silicon carbide crystals through sublimation. The process can be divided into mixing and heating as well.
Mixing: Powdered silicon and carbon are placed in a graphite crucible.
Heating: The crucible is heated to high temperatures of about 2000°C in a vacuum or inert gas environment.

Chemical Vapor Deposition (CVD)

CVD is a method of producing SiC using a gas-phase reaction. The steps are listed below.
Feedstock: Introduce SiC precursors, such as silicon tetrachloride (SiCl4), into a high-temperature reactor.
Reaction: React the precursors with a carbon-containing gas, such as methane (CH4), to form SiC.

FAQ

 

Q: Are you a trading company or a manufacturer?

A: We are a manufacturer located in Anyang City, Henan Province. All our customers are from home and abroad. Looking forward to your visit.

Q: What is your production capacity and delivery date?

A: 3000 metric tons per month. We have stock and can meet customer requirements. Usually we can ship within 7-15 days after your payment.

Q: Is the price negotiable?

A: Yes, if you have any questions, please feel free to contact us. We will do our best to support customers who want to expand their markets.

Q: Can I have a sample order?

A: Yes, we welcome sample orders to test and check quality. Mixed samples are acceptable.

Q: What are your payment terms?

A: T/T OR L/C mainly.

Q: Is silicon carbide soluble in water?

A: Silicon carbide is insoluble in water. However, it is soluble in molten alkalis (such as NaOH and KOH) and also molten iron. Silicon carbide can be considered as an organosilicon compound.

Q: What is the difference between green and black silicon carbide?

A: Silicon carbide (SiC) is known as carborundum. It is available in a greenish color and a black color. The color difference is due to the purity of the silicon carbide, green SiC being higher purity. Green SiC is usually used in food contact applications.

Q: What is the shelf life of silicon carbide?

A: As long as the product is maintained in the original sealed container and stored in a cool, dry, ventilated area, our product will last indefinitely.

Q: What can dissolve silicon carbide?

A: Silicon carbide resists the attack of many acids due to the formation of a thin layer of silicon dioxide, however, SiC will dissolve in molten alkali.

Q: What are the limitations of silicon carbide?

A: Despite its high strength, silicon carbide ceramic is brittle, making it susceptible to fractures under mechanical stress or thermal shock. Its poor impact resistance limits its use in applications where sudden shocks or extreme pressure variations occur.
