A method for joining sections of a densified ceramic wherein the mechanical strength of the joint obtained is substantially equivalent to that of the ceramic materials joined, comprising the steps of; selecting two sections of a ceramic to be joined, subjecting the two surfaces to be joined to a cleansing process, positioning a thin layer of a preceramic polymer between the surfaces to be joined which converts on pyrolysis to an interlayer containing the constituents of the ceramics to be joined, subjecting the ceramic/preceramic polymer/ceramic assembly to a mechanical load so that the applied load acts perpendicular to the joint, heating the loaded assembly in an inert environment to a temperature sufficient to cause conversion of the preceramic polymer to a ceramic, and joining the ceramic materials, and cooling to room temperature.
