Barium Nitrate chemical formula Ba(NO3)2 is a salt of barium and the nitrate ion.
Barium Nitrate exists as a white solid at room temperature. It is soluble in water, and like other soluble barium compounds, is toxic and should be handled with care.
Baratol is an explosive composed of barium nitrate, TNT and binder; the high density of barium nitrate results in baratol being quite dense as well. Barium nitrate mixed with aluminum powder is highly explosive. It is mixed with Thermite to form Thermate-TH3, used in military thermite grenades. It is also used in the manufacturing process of Barium oxide, the vacuum tube industry and for green fire in pyrotechnics.
[edit] Barium nitrate health risks
Like all soluble barium compounds, barium nitrate is toxic by ingestion or inhalation. Symptoms of poisoning include tightness of muscles (especially in the face and neck), vomiting, diarrhea, abdominal pain, muscular tremors, anxiety, weakness, labored breathing, cardiac irregularity, and convulsions. Death may result from cardiac or respiratory failure, and usually occurs a few hours to a few days following exposure to the compound. Barium nitrate may also cause kidney damage[1].
Solutions of sulfate salts such as Epsom salts or sodium sulfate may be given as first aid for barium poisoning, as they precipitate the barium as the insoluble (and non-toxic) barium sulfate.
Inhalation may also cause irritation to the respiratory tract.
While skin or eye contact is less harmful than ingestion or inhalation, it can still result in irritation, itching, redness, and pain.
