SiC Sealing Part

SiC Sealing Part plays a key role in semiconductor processing. Its excellent material properties and reliable sealing effect not only improve production efficiency, but also ensure product quality and safety.

Main Advantages of Silicon Carbide Sealing Part:

Excellent Corrosion Resistance: Among advanced ceramic materials, VeTeksemi SiC Sealing Part may have the best corrosion resistance in acidic and alkaline environments. This unparalleled corrosion resistance ensures that SiC Sealing Part can operate effectively in chemically corrosive environments, making it an indispensable material in industries that are often exposed to corrosive substances.

Lightweight and Strong: Silicon Carbide has a density of approximately 3.2 g/cm³, and despite being a lightweight ceramic material, the strength of silicon carbide is comparable to that of diamond. This combination of lightness and strength improves the performance of mechanical components, thereby increasing efficiency and reducing wear in demanding industrial applications. The lightweight nature of SiC Sealing Part also facilitates easier handling and installation of the components.

Extremely high hardness and high thermal conductivity: Silicon Carbide has a Mohs hardness of 9~10, comparable to diamond. This property, combined with high thermal conductivity (approximately 120-200 W/m·K at room temperature), enables SiC seals to function in conditions that would damage inferior materials. SiC's excellent mechanical properties are maintained at temperatures up to 1600°C, ensuring that SiC seals remain robust and reliable even in high-temperature applications.

High Hardness and Wear Resistance: Silicon Carbide is characterized by strong covalent bonds within its crystal lattice, giving it high hardness and a considerable elastic modulus. These properties translate into excellent wear resistance, reducing the likelihood of bending or deformation even after long-term use. This makes SiC an excellent choice for SiC sealing parts that are subjected to continuous mechanical stress and abrasive conditions.

Protective Silicon Dioxide Layer Formation: When exposed to temperatures of approximately 1300°C in an oxygen-rich environment, Silicon Carbide forms a protective silicon dioxide (SiO₂) layer on its surface. This layer acts as a barrier, preventing further oxidation and chemical interactions. As the SiO₂ layer thickens, it further protects the underlying SiC from other reactions. This self-limiting oxidation process gives SiC excellent chemical resistance and stability, making SiC seals suitable for use in reactive and high-temperature environments.

Versatility in High-Performance Applications:Silicon Carbide's unique properties make it versatile and efficient in a variety of high-performance applications. From mechanical seals and bearings to heat exchangers and turbine components, SiC Sealing Part's ability to withstand extreme conditions and maintain its integrity makes it the material of choice in advanced engineering solutions.
