METHOD OF FORMING GLASS BONDED JOINT OF BETA-ALUMINA AND OTHER CERAMIC AND JOINT FORMED THEREBY A method of producing a joint between a betaalumina electrolyte tube and alpha-alumina flange with a glass bonding agent in a solid annular bead form devoid of additives such as a coupling agent or the like capable of being heated when subjected to microwave energy which comprises utilizing in the heating step a source of microwave energy rather than a gas flame or electrical resistance heat source so as to heat the beta-alumina tube by microwave energy for a time period sufficient to enable the heat generated in the beta-alumina tube to be conducted tog lass bead and the alpha-alumina flange and heat the glass bead to a temperature above the glass deformation point, and allowing the tube to cool to solidify the glass bead in intimately penetrating relation to the surfaces of the beta-alumina tube and alpha-alumina flange engaged thereby so that the glass forms a bond between the beta-alumina tube and the alphaalumina flange characterized by a fusion of the glass within the engaged beta-alumina and alpha-alumina. |
