Aluminium chloride (AlCl3), is a chemical compound. It is a white or yellow crystalline solid. It melts at a low temperature. It is made by reacting aluminium oxide with hydrochloric acid. The anhydrous (without water) form may be made by reacting aluminium and chlorine. It is used in the making of chemicals. It is also used in deodorants. It can cause slight irritation.
