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.
A process of producing a hard-to-sinter oxyacid salt crystal on, and joined to, a ceramic base, the process comprising the steps of: forming a metal film on a ceramic base; anodizing the metal film to form a porous oxide film having numerous micropores extending through the entire thickness thereof; melting a hard-to-sinter oxyacid salt such as a sulphate or a carbonate on the porous oxide film, thereby causing the porous oxide film to be impregnated with a melt of the salt; and then cooling the ceramic base, together with the oxide film, to form a crystal of the hard-to-sinter oxyacid salt joined to the ceramic base.
