Aluminum nitride ceramics play various important roles in the aerospace field

This includes but is not limited to the following aspects:

Thermal structural components: Aluminum nitride ceramics due to their excellent high-temperature resistance performance

And widely used in the manufacturing of thermal structural components for aerospace spacecraft

These thermal structural components include spacecraft insulation shields, thermal protection plates, thermal shields, etc

Used to protect spacecraft from the influence of high-temperature airflow during re-entry into the atmosphere.

Guidance system: Aluminum nitride ceramics due to their high hardness, high thermal conductivity, and chemical stability

It is also applied in the guidance system of spacecraft

For example, in missile guidance systems

Aluminum nitride ceramics can be used as components such as bearings and sliders in inertial navigation systems

To ensure the stability and accuracy of the system

Engine components: Aluminum nitride ceramics are also used as key components in aerospace engines

Such as nozzles, flow deflectors, etc. These components need to have good high-temperature resistance and chemical stability

To withstand extreme conditions of high temperature and pressure in the engine, and ensure the performance and safety of the engine.

Infrared window: in some remote sensing satellites and missile systems

Aluminum nitride ceramics are also used as infrared window materials

Used to transmit infrared signals and protect optical systems from external environmental influences

Aluminum nitride ceramics have good optical transparency and chemical stability

Can meet the strict requirements of infrared sensor systems for optical materials

Overall, the role of aluminum nitride ceramics in the aerospace field is very important

Mainly reflected in its applications in thermal structural components, guidance systems, engine components, and infrared windows, etc

Provided critical support for the performance, stability, and safety of spacecraft
