This is a white, crystalline substance. It is a salt made of aluminum and nitric acid, which means that it is both soluble in water and stable in the air. It does not produce any odor or vapors, and it is non-flammable. Aluminum nitrate is slightly toxic to humans, particularly in concentrated doses.
The most notable thing about this about this substance is that it is a strong oxidizing agent. This makes it an ideal material for various industrial processes, including leather tanning and petroleum refining. It can also be included in antiperspirants as a means of blocking odors. Finally, it can be used in corrosion inhibitors.
Although aluminum nitrate is not highly toxic to humans, it still must be handled with care. Gloves, eye protection, and a breathing mask are recommended, as it can cause significant irritation if inhaled or if it comes into direct contact with the skin or eyes.
