  • Method of forming glass bonded joint of beta-alumina
    Patent number: 4792348
    Abstract: A method of producing a joint between a beta-alumina 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 to glass 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 alpha-alumina flange characterized by a fusion of the glass within the engaged beta-alumina and alpha-al
