ABSTRACT:
A method for the adhesive bonding of refractory parts wherein the refractory parts used are porous or capable of becoming porous by thermal treatment; a layer of thickness between 0.1. and 1 mm is interposed between the refractory parts, which layer is essentially formed of an adhesive which, after thermolysis, leaves a porous refractory residue, and fillers constituted by refractory particles of dimensions varying between 1 and 150 microns; the adhesive is thermolyzed so that a porous bond containing the said fillers is made between the porous refractory parts; then the assembly consisting of the refractory parts and the porous bond is densified by chemical vapor deposition of a refractory material.
