Large-sized mirrors for power optics - IOPscience

We study the feasibility of creating cooled large-sized mirrors from such materials as invar, silicon carbide, and carbon–silicon–silicon carbide composite. A method for large-sized mirror mass reduction is suggested based on the utilization of multilayered cellular and porous structures, which greatly decreases the weight of the mirror and

Black silicon carbide powders, bulk wholesale and retail

Black silicon carbide (SiC) is a semi-friable abrasive often used for general abrasive appliions in bonded abrasive tools, lapping, polishing, tock tuling, glass etching and frosting.  It is extremely resistant to wear, chemicals, and corrosion, making it excellent for sandblasting nozzles, furnace components, engine components, high tech ceramics, etc.  It is also an

Lightweight silicon carbide mirror - Hughes Aircraft Company

A lightweight mirror comprises a silicon carbide (SiC) foam core having a bulk density of approximately five percent. The mirror further comprises two solid facesheets each of which is integrally formed upon a surface of the SiC foam core, the facesheets being comprised of SiC.
