SOLUTIONS OF ALUMINUM IN LIQUID LITHIUM - ELECTRICAL-RESISTIVITY OF LIQUID ALLOYS

The electrical resistivity of solutions of aluminium (up to 15.76 mol% Al) in liquid lithium has been measured by a four-point capillary method from the melting point of lithium, 180.5 degrees C, to 440 degrees C. Aluminium increases linearly the resistivity of liquid lithium by a relatively large amount; 5.9 x 10(-8) Ohm m (mol% Al)(-1) at 320 degrees C to 5.7 x 10(-8) Ohm m (mol% Al)(-1) at 440 degrees C. These relatively large values make the resistivity technique potentially useful for monitoring the concentration of aluminium during chemical reactions in these metallic solutions.
