A method for purifying liquid lithium to remove unwanted quantities of nitrogen or aluminum. The method involves precipitation of aluminum nitride by adding a reagent to the liquid lithium. The reagent will be either nitrogen or aluminum in a quantity adequate to react with the unwanted quantity of the impurity to form insoluble aluminum nitride. The aluminum nitride can be mechanically separated from the molten liquid lithium.

A method for purification of liquid lithium by precipitation of aluminum nitride formed from an unwanted quantity of an impurity in the form of either aluminum or nitrogen present in the liquid lithium, comprising the following steps: adding a reagent to the liquid lithium in the form of a stoichiometric quantity of either nitrogen or aluminum to react with the unwanted quantity of impurity in the form of either aluminum or nitrogen, respectively, to form insoluble aluminum nitride; permitting the reaction to continue until completed; and separating the resulting precipitate of aluminum nitride from the liquid lithium.
