REACTION-SINTERED SILICON CARBIDE: NEWLY DEVELOPED MATERIAL FOR LIGHTWEIGHT MIRRORS

摘要

Newly developed high-strength reaction-sinteredrnsilicon carbide is an attractive material for lightweightrnoptical mirror with two times higher bending strengthrnthan other SiC materials. The polished surface has nornpore and is suited to visible region as well as infraredrnwithout CVD SiC coating. The fabrication process, withrnlow temperature and small shrinkage, is also suited torndevelop large scale objects.
