Abstract

PURPOSE: To prevent transformation of crystal structure of solid electrolyte, by forming a gas-impervious heat-resistant film in the low temperature region of solid electrolyte, in an exhaust gas oxygen concentration detector using partially stabilized zirconia as the solid electrolyte.
CONSTITUTION: On the outside (the side in contact with exhaust gas) of a solid electrolyte consisting of cup-shaped partially stabilized zirconia with one end opened and the other end closed, being installed in a cylindrical housing 7, is formed a second electrode (porous) 3 of thin film measuring about 1 μ in thickness, while a gas-impervious heat-resistant film 4 made from galss material is formed in the part free of the second electrode 3 (the low temperature part becoming about 150 to 600°C when in use). By thus forming the film 4, of the conditions of crystal transformation of the partially stabilized zirconia, the temperature of 150 to 600°C (a) and the contact with reducing gas (b), the condition (b) is not established even if the exhaust gas becomes a reducing one, because the contact with the gas is prevented, so that the crystal transformation may be prevented.
