| Abstract: | The properties of four materials for space camera, such as ULE, Zerodur, Be and silicon carbide(SiC),are compared. The result shows that the variety properties of SiC are excellent,and so SiC ceramic is the best material for space camera mirror.Four fabrication process of SiC and the development of large scale light-weighted SiC mirror blank in home and abroad recently are presented. |
