Abstract
A method for bonding silica containing materials uses a mixture of ultrasonically treated silica powder and a suspension liquid to provide a bonding material. Once applied to the bonding surfaces of silica containing components the mixture is dried and then heated. Upon cooling the mixture provides a solid bonding between the components. The bonding procedure minimizes the mount of localized heating required to bond the material and thereby prevents distortion of silica components as they are bonded.
