ABSTRACT:
A method for forming a homogeneous bond between silicon nitride ceramics is disclosed which comprises melting a bonding composition placed between the surfaces to be bonded. The bonding composition is specifically selected to provide in the bond or joint the same chemical constituents found intergranularly in the silicon nitride materials to be bonded. The resultant bond is as strong or stronger than the silicon nitride materials bonded.
