Macor ceramic seals for aerospace applications

Macor ceramic seals have multiple applications in the aerospace industry.

Sealing of engine components
-Combustion chamber sealing: Macor ceramics have excellent high temperature resistance and chemical stability, which can maintain stability in the high temperature, high pressure, and corrosive environment of the engine combustion chamber, effectively preventing combustion gas leakage and ensuring engine combustion efficiency and safety.
-Turbine blade seal: Its high strength, high hardness, and good wear resistance enable it to withstand the friction and impact forces generated by the high-speed rotation of turbine blades, while maintaining sealing performance, reducing energy loss, and improving the overall performance of the engine.

Spacecraft cabin sealing
-Door and window sealing: The low thermal conductivity and good electrical insulation performance of Macor ceramics make them play an important role in sealing spacecraft doors and windows. It can effectively block the transfer of external heat, maintain stable cabin temperature, and prevent electromagnetic radiation from entering the cabin, ensuring the safety of internal equipment and personnel of the spacecraft.
-Sealing at cabin connections: At the cabin connection of spacecraft, Macor ceramic seals can withstand the vibrations and impacts generated during high-speed flight, ensuring the sealing between cabins and preventing gas leakage and external environmental impact on the cabin environment.

Electronic device sealing
-Sensor sealing: The high dielectric strength and low dielectric loss of Macor ceramics make it an ideal material for manufacturing high-temperature, high-frequency, and high-precision sensors. In aerospace sensors, such as sensors that monitor engine operating status and measure flight parameters, Macor ceramic seals can protect sensors from high temperatures, radiation, and chemical corrosion, ensuring sensor stability and reliability.
-Electronic component packaging and sealing: In spacecraft and satellites, Macor ceramics are used to protect sensitive electronic components from high temperatures, radiation, and other external factors. It can provide a good sealing environment for electronic components, prevent the invasion of gases, liquids, and small particles, and ensure the normal operation of electronic devices in extreme environments.

Other applications
-Vacuum sealing: Macor ceramic material has zero porosity, does not adsorb gases, and has no substance exchange between the inside and outside, making it suitable for ultra-high vacuum environments or various applications that require gas sealing. For example, in the vacuum experimental equipment and vacuum pipelines of spacecraft, Macor ceramic seals can effectively maintain a vacuum environment and prevent gas leakage.
-Optical system sealing: In aerospace optical systems, such as satellite optical systems, spacecraft observation windows, etc., Macor ceramic seals can protect optical components from external environmental influences and maintain stable optical performance. Its excellent chemical and thermal stability enables it to work in harsh environments for a long time, improving the observation accuracy of spacecraft.
