  • Solid electrolyte gas sensor and process of producing joined body of ceramics and hard-to-sinter oxyacid salt
    Patent number: 5547556
    Abstract: A solid electrolyte gas sensor comprising: a base plate of a solid electrolyte, on which are disposed a detecting electrode for detecting a selected gas, a reference electrode, and a conductor portion for external connection such as an outer lead.A process of producing a joined body of a ceramic member and a hard-to-sinter oxyacid salt crystal, the process comprising the steps of: impregnating a melt of a hard-to-sinter oxyacid salt such as a sulphate or a carbonate into a porous ceramic plate having micropores extending through the entire thickness thereof; then cooling the impregnated ceramic plate to form a composite plate composed of the ceramic plate with the micropores filled with a crystal of the hard-to-sinter oxyacid salt; and joining the composite plate to a ceramic base.
    Type: Grant
    Filed: May 2, 1995
    Date of Patent: August 20, 1996
    Assignee: Shinko Electric Industries Co., Ltd.
    Inventors: Tsuyoshi Kobayashi, Misa Saitoh
