Abstract

1281718 Measuring oxygen content in liquid metals METALLURGIE HOBOKEN RST INTERNATIONAL METALS Ltd and F D RICHARDSON 21 July 1969 36549/69 Heading G1N An electro-chemical cell for measuring oxygen in molten copper, lead, tin and silver, comprises a solid electrolyte A 1 , A 2 in the form of a rod or strip cemented into one end of a metal or cement protective tube C. As shown, platinum leads 3, 4 are wound round the upper ends of the rods A 1 , A 2 which are first platinized or sheathed in platinum foil. Two cements 6, 7 separated by an alumina ring B may be used or one cement without a ring B may be used. Examples of suitable materials are given. Tongue E is dipped into the molten metal before the cell to reduce thermal shock. Independent measurements of the potentials X 1 -Y and X 2 -Y give a check that the cell is working accurately. A third solid electrolyte and lead may be provided. A stream of reference gas (e.g. air) passes as shown by arrows 8 and 9. Alternatively Figs. 2 and 3 (not shown) the reference oxygen may be supplied by a mixture of nickel and nickel oxide or copper and cuprous oxide in contact with the upper end of the solid electrolyte and a stream of argon or nitrogen is used to sweep away air.
