Advantages of Ceramic Seal Ring

● High wear resistance
● High corrosion resistance
● High-temperature resistance
● Dimensional stability and aging resistance
● Excellent sliding properties (tribology)
● Biocompatibility (for use in hygiene and the food and beverage industry)
Electrical seal systems: The highest performance electrical seal systems employ Ceramic Seal Ring for its exceptional resistance to thermal and mechanical shock, as well as corrosion. 

● Medical implant devices: exceptional corrosion resistance and biocompatibility are required by medical implant devices. Ceramic Seal Ring plays a critical role in implantable electronic devices. Researchers and doctors have created a wide array of implantable electronic devices including defibrillators, cochlear implants, and neurostimulators. Feedthroughs for implanted devices must be hermetic, with a leak-tight ceramic seal ring around each pin. 

● Aerospace applications: high resistance to thermal and mechanical shock is necessary for many aerospace applications. Alumina ceramic components are ideally suited for aerospace applications, due to their ability to withstand the high temperatures, vibration and mechanical shock typically found in aircraft engines and other high-stress locations. Ceramic Seal Ring is commonly found in seals for gas turbine engine thermocouples, fuel line assemblies, and fire detection system terminations.

● Automotive and vehicle engineering: Ceramic pump Seal have excellent wear resistance, dimensional stability and a reduction in moving mass increase performance of the vehicle while simultaneously decreasing noise emission levels and extending the service life of all types of pumps in vehicles. For instance in coolant pumps, electronic fuel pumps and high-pressure pumps for diesel engines all have Ceramic Seal Ring.

  • Positive Temperature Coefficient is a kind of semiconductor thermal ceramics. Its characteristic is sensitive to temperature. It shows negative resistance when it is lower than the Curie temperature; when it reaches the Curie temperature, its resistance value begins to increase sharply. When used as a heating material, it has the following superior characteristics: automatic constant temperature, no oxygen consumption, corrosion resistance, etc. PTC ceramics are mainly doped barium titanate semiconductor ceramics, which have relatively small ionization energy and can be thermally excited to generate conductive carriers at room temperature, thereby forming semiconductors.
