Method for bonding components made of high silica material

Abstract

The present invention relates to a method for bonding components made of high silica material by way of integral joining by forming a high-silica bonding mass between connecting surfaces of the components. A method is provided which permits an inexpensive production of a mechanically and thermally stable composite of components made of a high silica material, particularly for large-area bonded connections for which a contact pressure of more than 5 N/cm2 is applied while the connecting surfaces are being fixed, and/or the path length for possible degassing products from the bonded connection is more than 150 mm. This object is achieved according to the invention in that the SiO2 bonding mass is used in dry form either right from the beginning or at least the SiO2 bonding mass is dried on the connecting surfaces before the joining process and the surfaces to be bonded are subsequently brought into contact and a firm composite is created by way of heating with formation of a SiO2 containing bonding mass.
