Methods of forming a mirror by bonding a faceplate to a core structure using adhesive formulations that include fused silica particles having diameters that range between 1 to 60 micrometers with an average diameter of the silica particles being between 8 to 10 micrometers. The adhesive formulation further includes an activator including 25 to 50 weight % sodium silicate, 25 to 50 weight % sodium hydroxide and a liquid. The fused silica particles constitute 70 to 80 weight % of the adhesive formulation and the activator constitute 20 to 30 weight % of the adhesive formulation.

Methods of manufacturing mirrors

Methods of forming a mirror by bonding a faceplate to a core structure using adhesive formulations that include: (1) a binder comprising 40 to 60 weight % monoaluminum phosphate and 40 to 60 weight % water, the binder constituting 25 to 35 weight % of the adhesive formulation and, (2) a composition that includes a first set of particles having a coefficient of thermal expansion equal to or less than 0.05 ppm/&#xb0; C. and diameters between 1 to 60 micrometers and a second set of particles having a coefficient of thermal expansion equal to or less than 0.05 ppm/&#xb0; C. and diameters between 0.05 to 1 micrometers, the first set of particles constituting 80 to 85 weight % of the composition, the second set of particles constituting 15 to 20 weight % of the composition; the composition constituting 65 to 75 weigh % of the adhesive formulation.
