Method and composition for assembling together refractory bodies

Claim 1

A PROCESS OF ASSEMBLING TOGETHER REFRACTORY BODIES OF THE CLASS CONSISTING OF CARBIDES, NITRIDES AND BORIDES OF HIGH MELTING POINT METALS, CONSISTING IN THE FOLLOWING STEPS: MIXING TOGETHER A POWDERED METAL SELECTED FROM THE CLASS CONSISTING OF TITANIUM, ZIRCONIUM, TUNGSTEN, MOLYBDENUM AND TANTALUM, AND A METALLOID SELECTED FROM THE CLASS CONSISTING OF CARBON AND BORON, SAID METAL AND METALLOID BEING MIXED IN SUBSTANTIALLY STOICHIOMETRIC PROPORTIONS FOR FORMATION OF THE RESPECTIVE METAL-METALLOID COMPOUND; ADDING THERETO AN ORGANIC PLASTIC BINDER WHICH IS LIQUID AT ORIDNARY TEMPERATURES SELECTED FROM THE GROUP CONSISTING OF THOSE THAT SOLIDIFY BY HEATING AND IN THE COLD BY CATALYTIC ACTION, AND WHICH BINDER IS CAPABLE OF ELIMINATION BY HEATING TO A TEMPERATURE OF APPROXIMATELY 500* C., THERE BEING USED A SUFFICIENT QUANTITY OF SAID BINDER SO THAT THE RESULTANT PASTE HAS THE PLASTICITY OF CEMENT MORTAR USED IN MASONRY; COATING THE SURFACES OF THE BODIES TO BE ASSEMBLED WITH THIS PASTE; ASSEMBLING SAID BODIES TOGETHER; AND THEREAFTER HEATING THE ASSEMBLED PARTS TO APPROXIMATELY 1900* C. TO SINTER THE METAL-METALLOID MIXTURE AND THEREBY JOIN SAID BODIES TOGETHER.
