| description | PCT No. PCT/JP81/00214 Sec. 371 Date Mar. 29, 1982 Sec. 102(e) Date Mar. 29, 1982 PCT Filed Sep. 3, 1981 PCT Pub. No. WO82/00892 PCT Pub. Date Mar. 18, 1982.A sensor comprising a solid electrolytic having oxygen ion conductivity to measure the amount of oxygen in molten metal by forming an oxygen concentration cell in which the solid electrolytic element is coated on the surface thereof with mixture which is composed of Al2O3 powders and metallic fluoride powders such as MgF2 or CaF2. The present coating does not exfoliate at immersing the sensor into the molten metal and fully maintains wettability of the solid electrolytic element 1 and the molten metal, and since it does not hinder oxygen ion conductivity of the solid electrolytic element 1, the sensor rapidly reaches up to the thermal and electrical equilibrium state, thereby to obtain satisfactory emf wave. |
