Barium nitrate is the inorganic compound with the chemical formula Ba(NOiii)2. Information technology, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is usually used in pyrotechnics.[four]
Manufacture, occurrence, and reactions [edit]
Barium nitrate is manufactured by 2 processes that showtime with the main source material for barium, the carbonate. The first involves dissolving barium carbonate in nitric acid, assuasive any iron impurities to precipitate, then filtered, evaporated, and crystallized. The 2d requires combining barium sulfide with nitric acid.[4]
It occurs naturally as the very rare mineral nitrobarite.[5] [vi]
At elevated temperatures, barium nitrate decomposes to barium oxide:
- 2Ba(NO3)2 → 2BaO + 4NOtwo + O2
Applications [edit]
Barium nitrate is used in the product of BaO-containing materials.
Military [edit]
Although no longer produced, Baratol is an explosive composed of barium nitrate, TNT and binder; the high density of barium nitrate results in baratol being quite dumbo too. Barium nitrate mixed with aluminium pulverization, a formula for flash pulverization, is highly explosive. It is mixed with thermite to grade Thermate-TH3, used in military thermite grenades. Barium nitrate was also a primary ingredient in the "SR 365" incendiary charge used by the British in the De Wilde incendiary ammunition with which they armed their interceptor fighters, such as the Hawker Hurricane and Supermarine Spitfire, during the Battle of Britain.[7] It is also used in the manufacturing process of barium oxide, the vacuum tube manufacture and for green fire in pyrotechnics.
Safety [edit]
Like all soluble barium compounds, barium nitrate is toxic by ingestion or inhalation.[viii]
Solutions of sulfate salts such equally Epsom salts or sodium sulfate may exist given every bit get-go aid for barium poisoning, as they precipitate the barium every bit the insoluble (and non-toxic) barium sulfate.
Inhalation may besides crusade irritation to the respiratory tract.
While pare or centre contact is less harmful than ingestion or inhalation, it can all the same result in irritation, itching, redness, and hurting.
The Occupational Prophylactic and Wellness Administration and the National Institute for Occupational Safe and Health have set up occupational exposure limits at 0.5 mg/m3 over an eight-60 minutes time-weighted average.[ix]
