Abstract:
1. A method for bonding together a plurality of refractory components, each having at least one surface to be bonded, the method comprising: (a) polishing each surface to be bonded to a surface roughness Ra of 200 nm or finer; (b) directly contacting the surfaces to be bonded to form an unbonded refractory substrate; (c) firing the unbonded refractory substrate; (d) subjecting the surfaces to be bonded to a compressive force during firing; and wherein the refractory components are chosen from the group consisting of zircon components, alumina components, and fused cast zirconia components and the unbonded refractory substrate is fired at a temperature and for a time sufficient to sinter the refractory components and effect bonding at the surfaces.
