The joining of advanced ceramics makes it possible to manufacture components with complex shapes, which cannot be made in a cost-effective manner using the existing techniques, i.e., green state shaping and/or machining. A new technique for the green state joining of alumina ceramics was developed simply by using a paste of ceramic slurry. The interlayer of the joints has the same composition as the parent green bodies, and therefore, the mechanical properties of the joint are comparable to those of the bulk material. This process can be applied to the joining of various advanced ceramics
