  • Lightweighted telescope mirrors: Outstanding properties

    A chemical vapor silicon carbide is deposited on a heated substrate at temperatures higher than 1300C. As a result, a beta-SiC is obtained. This polytype of SiC is almost fully dense and has very fine columnar grains. Beta-SiC is then deposited on a graphite or SiC bulk material during "encapsulating" process.
