METHOD FOR JOINING CERAMIC AND METAL-CERAMIC HEATING ELEMENTS TO ELECTRICAL TERMINALS BY MICROPYRETIC SYNTHESIS, COMPOSITIONS FOR ELECTRICAL TERMINALS AND HEATERS COMPRISING THE SAME

摘要

A method for joining a ceramic or metal ceramic electrical heating element (1) to an electrical terminal (2) is disclosed, the heating element having been manufactured using micropyretic synthesis, the method for joining comprising the steps of preparing the electrical terminal by blending a combustible mixture and fashioning the mixture into a desired wet and uncombusted shape for the terminal, attaching the terminal to the element, drying the terminal portion of the terminal-element attachment and combusting the terminal portion of said terminal-element attachment by ignition at a temperature between about 150 DEG C and 1800 DEG C. An electrical terminal is disclosed, the terminal having been formed by micropyretic synthesis of a specific combustible composition. A heating element assembly for a heater is disclosed comprising a first and a second ceramic or metal ceramic electrical terminals, a plurality of ceramic or metal ceramic heating elements and a plurality of ceramic or metal ceramic coolers (3) which are used to connect said plurality of heating elements to each other.
