Abstract
Improvements in process control during the production and reclamation of aluminum alloys can be achieved through in-situ measurement of the magnesium content in the molten alloy. Electrochemical sensors are compact, can be inserted directly into molten aluminum, and produce a continuous direct current voltage proportional to the logarithm of the magnesium content. This article describes and compares electrochemical magnesium sensors based on three different electrolytes— MgCl2-CaCl2, MgF2, and β″ alumina.
