Silicon carbide: the most promising new light mirror material in the future

With the continuous development of science and technology, countries around the world have launched in-depth research in the field of outer space. This research work can only be realized with the help of a certain reflective optical system.

As one of the key parts of the reflective optical system, the mirror has high requirements for the mirror body materials. It not only needs to meet the requirements of optical applications, but also based on the harsh environment in space. It must also have the characteristics of small thermal deformation coefficient, good radiation resistance, small surface roughness, easy processing, low cost and so on.

In recent years, silicon carbide material is becoming the most promising new light mirror material with its excellent physical and technological properties. Due to the late start of optical application of silicon carbide and its composites in China, although the preparation of related materials has basically achieved the level of synchronization with the world, but the processing is still in a relatively backward stage.

However, in recent years, with the development and improvement of the main research institutions in China, the self-developed SiC mirror has also been applied in the space optical system, and achieved good expected results. It is believed that with the continuous attention paid to aerospace industry and military industry by all countries in the world, the application of SiC Based reflectors will be more and more extensive in the future.
