Tough ceramic-glass composite joints are formed between ceramic tubes and headers, thereby greatly extending the design possibilities of solid electrolyte devices. A composite ceramic-glass joint is formed from a mixture of glass powder and ceramic powder in suspension in a low viscosity liquid, allowing the liquid to evaporate, and firing the mixture to a temperature which enables the glass to form a hermetic joint. The low viscosity suspension results in the absence of voidage or unwanted residues in the joint. A minimal amount of binder is facilitated by fine ceramic particles which themselves function as a binder. A low viscosity suspension flows easily and can be dispensed by means of a fine nozzle and the suspension is retained either by surface tension or by some form of containment. This is useful for joining of an array of tubes to a common header containing a corresponding array of holes. |
