| Abstract Scope |
We report our recent progress in the development of high quality transparent ceramic materials. There are numerous applications operating in very harsh environments that require rugged windows. MgAl2O4 spinel and sesquioxides are excellent candidates for these applications due to their high mechanical strength, wide transmission range, and isotropic structure. Here, we provide an update of the results of the synthesis, scale up process, and applications of ultra-high purity spinel, undoped/RE-doped Sesquioxides, and non-oxide ceramics such as beta-SiC developed for mid-IR ceramic window material for an extreme environment. Various densification methods used to fabricate high quality optical ceramics are also presented. |
