From the analysis of the known data and the results of investigations carried out, advantages and limitations of different methods of unglue bonding of glass-ceramic parts like Zerodur with ultra low coefficient of thermal expansion (CTE), are presented. It seems that by (quality-cost) criterion the solid-phase bonding of polished parts (SBPP) with the use of thin layer aluminum or its alloys to bond the ceramic optical parts is favorable. In optimal case the metal coatings for glass-ceramics bonding should be multilayer. The examples of SBPP bonding of glass-ceramic parts are presented which are close to strength characteristics of a monolith. It is shown that for bonding quality control the optical methods, including thermo-vision, can be applied.
