The analysis of literature data and the set of experimental results allow one to consider SiC-ceramics and glassceramics as the most perspective materials for light-weight telescope mirrors. The developed technology of solid-phase bonding of polished details with the help of nano-dimensional vacuum coatings (SBPD-tech-nology) enables one to realize "sandwich"-constructions of the light-weight mirrors both of glass ceramics and of the combined constructions, SiC-ceramics (basis) – glassceramics (top working layer).
