Applications

When come to moisture or water, aluminum(III) sulfide form hydrogen sulfide and aluminum hydroxide. When heating, it erode porcelain and could be restored by iron and hydrocarbon to get aluminum metal.  Sulphur and aluminum sulphate got after compounding with SO2.

Storage

Aluminum(III) sulfide should store in container in dry, cool, ventilate place. It should avoid oxides, moisture, water, acids.
