Types of Silicon Carbide Ceramics
 
 

The silicon carbide ceramics produced by our company mainly include the following types:

 

Silicon Carbide Sealing Ring

The important characteristics of silicon carbide sealing ring is excellent wear resistance and corrosion resistance, and SiC seal ring has good sealing performance even in acid or alkali corrosive environments.

 
 

Silicon Carbide Ceramic Wafer Boat

Silicon carbide ceramic wafer boat is a high-performance semiconductor material that plays an irreplaceable role in cutting-edge technology fields such as semiconductor chip manufacturing and photovoltaic cell production.

 
 

Silicon Carbide Cavity

The silicon carbide cavity is a key component designed and manufactured to meet the needs of various high-temperature industrial applications.

 
 

Sic Ceramic Tube

SiC ceramic tubes have remarkable qualities. Because of their extreme hardness, they are resistant to wear and long-lasting. Their exceptional thermal conductivity allows them to withstand temperatures as high as 1500–1800°C.

 

 

Advantages of Silicon Carbide Ceramics
 
碳化硅陶瓷管
 

Excellent High-Temperature Performance

Silicon carbide ceramics have an extremely high melting point of up to 2700°C, enabling them to maintain structural stability and strength even under extreme heat conditions. This property makes SiC ceramic an ideal high-temperature-resistant material, widely used in applications such as SiC tubes, SiC burner nozzles, and SiC kiln furniture.

 

Superior Corrosion Resistance

Silicon carbide exhibits excellent chemical stability, as the strong covalent bonds between Si and C atoms prevent reactions with acids, alkalis, and other corrosive substances. This exceptional corrosion resistance makes SiC ceramic a preferred material in harsh chemical environments, particularly for applications requiring long-term durability.

High Hardness and Strength

The high hardness of SiC ceramic is due to the strong covalent bonding between silicon (Si) and carbon (C) atoms. This bonding structure makes silicon carbide ceramics highly resistant to compression and deformation. With a hardness significantly higher than that of alumina (Al₂O₃), aluminum nitride (AlN), silicon nitride (Si₃N₄), and zirconia (ZrO₂), high-hardness silicon carbide is widely applied in SiC mechanical seals, SiC bulletproof plates, and other wear-resistant components.

 

Outstanding Thermal and Electrical Conductivity

Compared to alumina, zirconia, and silicon nitride ceramics, SiC ceramic offers higher thermal and electrical conductivity. Although its thermal conductivity is lower than that of aluminum nitride (AlN), SiC ceramic is widely used in high-power electronic components and heat dissipation systems, where efficient thermal management is necessary.

Precautions for Using Silicon Carbide Ceramics
 

Handling with Care
When transporting and installing silicon carbide ceramics, handle them with extreme care to avoid any collision or impact. These tubes are brittle and can easily crack or break. Use appropriate lifting tools and protective packaging to ensure their integrity.

 

Correct Installation
Before installation, make sure to check the dimensions and specifications of the tube to ensure it matches the requirements of the equipment. Install the tube according to the manufacturer's instructions, ensuring a proper fit and connection. Avoid forcing the tube into place, as this may cause stress and potential damage.

 

Operating Conditions
Operate the silicon carbide ceramics within the recommended temperature and pressure range. Exceeding these limits can lead to a reduction in the tube's performance and lifespan. For example, most silicon carbide ceramics are suitable for high-temperature applications, but it is crucial to stay within the specified temperature ceiling, typically around 1600°C - 1800°C depending on the specific material composition.

 

Media Compatibility
Ensure that the substances flowing through the tube are compatible with the ceramic silicon carbide material. Some chemicals may react with the tube, causing corrosion or other forms of damage. For instance, avoid contact with strong acids and alkalis unless the tube is specifically designed to resist such substances.

 

Packaging and Shipping

 

Packaging

Products with small sizes are generally packed in cartons, and the inside of the cartons is fixed with plastic foam.Large-size products are generally packed with plywood boxes. Different sizes of products have different packaging methods.

Shipping

We will help you to choose the best shipping way according to your detail requirements. By sea, by air, or by express, etc.

FAQ

 

Q: What is silicon carbide ceramic?

A: Silicon carbide ceramic is an engineering ceramic material with silicon carbide (SiC) as the main component, which is made by sintering, vapor deposition and other processes. It has high hardness (Mohs hardness 9.2-9.3), high temperature resistance (anti-oxidation temperature of more than 1600℃), wear resistance, corrosion resistance and excellent thermal conductivity, and is widely used in high-end manufacturing, energy, electronics and other fields.

Q: What are the main components of silicon carbide ceramics?

A: Silicon carbide (SiC), purity is usually ≥95%, and sintering aids (such as B, C, Al₂O₃, etc.) can be added according to application requirements.

Q: How are silicon carbide ceramics used in the semiconductor and electronics fields?

A: Power device substrates: Used to make third-generation semiconductor devices such as SiC MOSFET and IGBT, which are resistant to high voltage (≥1200V) and low high-frequency loss, and are used in new energy vehicles and charging piles.
Heat dissipation substrates: Heat dissipation bases for packaged chips, with high thermal conductivity, which solve the heat dissipation problems of 5G base stations and radar modules.
Semiconductor manufacturing equipment: etching chambers and wafer carriers, which are resistant to plasma corrosion and extend equipment life.

Q: What is the oxidation resistance of silicon carbide ceramics?

A: In air, it is almost not oxidized below 1000℃, and the oxidation rate increases significantly at 1600℃. A SiO₂ oxide film is formed on the surface, which can prevent further oxidation inside.

Q: How to detect the quality of silicon carbide ceramics?

A: Density test: Archimedes method measures density, ideal value ≥99% (hot pressing sintering).
Mechanical properties test: Three-point bending strength (≥400MPa), fracture toughness (≥4MPa・m¹/²).

Q: Can silicon carbide cut glass?

A: Silicon carbide wheels are useful for cutting glass, quartz, ceramics, titanium, tungsten, zirconium, uranium, beryllium and germanium, fiber, plastics (such as phenolics) and fiber-reinforced plastics.
