Blake, R D; Meek, T T

A method is described for producing a ceramic-glass-ceramic seal comprising the steps of: a. preparing a mixture comprising a glass sealing material, a coupling agent, and an oxidizer; b. applying the mixture to a plurality of ceramic workpieces for sealing; c. enclosing the ceramic workpieces with other such workpieces; d. surrounding the mixture and plurality of ceramic workpieces with an insulative material; e. microwaving the mixture and plurality of ceramic workpieces at a power, time and frequency sufficient to ignite the oxidizer and to cause a liquid phase seal to form; and f. allowing the seal and workpieces to cool, thereby securing a ceramic-glass-ceramic seal.
