Lithium Arsenide, Li₃As

Lithium Arsenide, Li₃As, is formed when a mixture of the elements in suitable proportions is heated to redness, or when lithium arsenate is reduced by heating with charcoal in an electric furnace. It is a dark brown crystalline substance of great reactivity. It is attacked by the halogen elements at the ordinary temperature with incandescence. It burns vividly when heated in oxygen; it reacts violently with nitric acid, and at a comparatively low temperature it reduces many metallic oxides.
