Alkali-metal azide is prepared and purified from a slurry of alkali-metal azide/alkali metal hydroxide double salt in liquid ammonia by settling a layer of double salt from the slurry, separating the balance of the slurry from the double salt layer, then dissolving the layer in water and recovering purified alkali-metal azide from the water solution by crystallization.
