Barium nitrate with chemical formula Ba(NO3)2 is a salt composed 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. It occurs naturally as the rare mineral nitrobarite.
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 aluminium powder, a formula for flash 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.
