Aluminum nitrate appears as a white, crystalline solid. Noncombustible but can accelerate the burning of combustible materials. If large quantities are involved or the combustible material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Fires that involve this material, produce oxides of nitrogen. Uses include, petroleum refining, dyeing, and leather tanning.

Deliquescent. Water soluble . Aqueous solutions are acidic.
The nonahydrate and other hydrated aluminum nitrates have many applications. These salts are used to produce alumina for preparation of insulating papers, in cathode tube heating elements, and on transformer core laminates. The hydrated salts are also used for extraction of actinide elements. Textiles (mordant), leather tanning, manufacture of incandescent filaments, catalyst in petroleum refining, nucleonics, anticorrosion agent, antiperspirant.
