Abstract
1,153,628. Determining properties of liquid metals. MINE SAFETY APPLIANCES CO. Nov.1 1966, No.48933/66. Heading G1N. The concentration of combined oxygen in a liquid alkali metal in a closed loop heat transfer system is measured by contacting the liquid metal with an electrode 6 of a metal that forms an oxide more stable than the oxide of the alkali metal and measuring the subsequent substantially linear rate of electrical resistance increase due to formation of oxide on the electrode. As shown, electrode 6 is attached to a rod 8 slidably engaged in a sleeve 10 mounted in a detachable section 16. A gate valve 18 enables section 16 to be isolated in the manner of an air-lock to prevent atmospheric contamination of the liquid metal when the electrode is introduced. Preferably, the electrode is totally immersed and the rod 8 is coated with an insulating refractory. The temperature is preferably kept constant. For greater sensitivity, the circuit may be completed through a second electrode immersed in the liquid metal. Examples of electrode metals are; Th, Mg, Be, Y, Al, Hf, Ce, Zr, Ti, Nb, Cr, Zn and Mn and those which are suitable for use with different liquid alkali metals (Li, Na, K, Rb, Cs) are tabled.
