Lithium antimonide, Li₃Sb

Since the direct combination of lithium and antimony is very violent, Lebeau recommends preparing the antimonide by the electrolysis of a fused mixture of lithium and potassium chloride with an iron cathode covered with antimony. It is a dark-grey, crystalline substance of a very reactive nature. Its density at 17° C. is 3.2, and its melting-point is 950° C. The compound is also formed by the action of antimony on a solution of lithium in liquefied ammonia.
