Non-oxide Ceramics – Silicon Carbide (SiSiC/SSiC)

The non-oxide ceramic silicon carbide (SiSiC or SSiC) is a ceramic material that is as hard as diamond and features many other important characteristics. The lightest and hardest ceramic material CeramTec offers is available as SSiC (sintered silicon carbide) and SiSiC (silicon infiltrated silicon carbide).

Metal Coated Mirror | II-VI Incorporated

A mirror is an object with a surface that has good specular reflection and is smooth enough to form an image. II-VI provides many types of mirrors, including plane mirrors (meaning the surface is flat) and curved mirrors (meaning the surface is curved, producing magnified or de-magnified images, focusing light, or distorting the reflected image).
