Solutions of aluminium in liquid lithium: electrical resistivity of liquid alloys
Abstract
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 °C, to 440 °C. Aluminium increases linearly the resistivity of liquid lithium by a relatively large amount; 5.9 × 10–8Ω m (mol% Al)–1 at 320 °C to 5.7 × 10–8Ω m (mol% Al)–1 at 440 °C. These relatively large values make the resistivity technique potentially useful for monitoring the concentration of aluminium during chemical reactions in these metallic solutions.
