Aluminum sulfide, also known as aluminium sulphide, is a compound of aluminum and sulfur with the formula Al2S3. A colorless or gray solid with an exceptional sensitivity to moisture, aluminum sulfide is not to be confused with the more widely used aluminum sulfate, Al2(SO4)3. Exposed to the atmosphere or other sources of moisture, aluminum sulfide will hydrolize into aluminum hydroxides and hydrogen sulfide gas. This makes careful storage and handling a priority.


Many of the most interesting applications of aluminum sulfide remain in the early research phases, with many researchers eager to explore its value in aluminum-sulfur energy story. 

  • Energy storage. A subject of research in the production of aluminum-sulfur batteries, a potentially superior alternative to lithium batteries.
  • Photovoltaics. Like several similar metal sulfides, aluminum sulfide may be of value for its photovoltaic properties at smaller scales.
  • Catalysis. Useful for its reactivity in producing several commercially or academically valuable compounds.
  • Aluminum source. Moderately water and acid soluble source for aluminum.
