ABSTRACT:
A process for joining ceramic parts comprises autoclaving a powdered ceramic composition to increase its hydrogen form contents to a concentration that serves to increase the composition's absorption of microwave energy during subsequent heating of the ceramic parts; coating the autoclaved ceramic composition on the surfaces of the parts to be joined together; and placing the coated surfaces of the parts to be joined together and focusing microwave energy at the joint between the parts in order to seal the joint by refiring and rereacting the parts, the microwave energy being of sufficient power and being uniformly applied to the joint for a sufficient period of time to seal the joint. An apparatus for joining ceramic parts with microwaves comprises a microwave ring furnace capable of encircling a joint area between ceramic parts having a circular cross section; at least one microwave guide attached to the microwave ring furnace with a microwave source connected to the microwave guide; and a rotation table for rotating the joint area of the ceramic parts within the microwave ring furnace.
