ABSTRACT:
A method for joining a ceramic or metal ceramic electrical heating element to a electrical terminal 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.degree. C. and 1800.degree. 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 element and a plurality of ceramic or metal ceramic coolers which are used to connect said plurality of heating elements to each other.
