BONDING BETWEEN QUARTZ GLASS WITH INORGANIC MATERIAL |
| 摘要 |
PURPOSE:To bond quartz glass with a high mechanical and chemical strength without strain and deformation of the quartz glass material, by heat bonding the quartz glass using a slurry-like blend consisting of a glass frit having specific physical properties and an organic binder. CONSTITUTION:A slurry-like blend consisting of a glass frit of homogeneous composition having about 19X10<-7>-21.5X10<-7>cm/cm deg.C linear expansion coefficient as well as a softening temperature of >=about 1,050 deg.C-<annealing temperature of the quartz glass and an organic binder is applied to mutual butting surfaces of plural pieces of quartz glass material and heated at a temperature of >=the above-mentioned softening temperature-<annealing temperature. The organic binder is heat cleaned by the heating and the quartz glass material is mutually bonded by fusion of the glass frit at the same time. High-accuracy mutual bonding of quartz material which has been considered as almost impossible can be readily carried out without residual organic compounds on the adhesive surfaces and causing strain as well as deformation of the quartz glass material. Thereby bonding can be carried out with an extremely high mechanical and chemical bonding strength. |
