| Chemical Properties | Back Directory | [Description]
Barium nitrate is a stable, strong oxidiser. It is incompatible with combustible material,
reducing agents, acids, acid anhydrides, and moisture-sensitive substance. Barium nitrate
is poisonous, is a respiratory irritant, and is hazardous if mixed with flammable materials.
Barium oxide plus zinc, aluminium and magnesium alloys are combustibles (paper, oil,
wood), acids, and oxidisers and is hazardous. Mixtures with finely divided aluminium–
magnesium alloys are easily ignitable and extremely sensitive to friction or impact.
Barium nitrate mixed with aluminium
powder, a formula for flash powder, is highly explosive. However, barium nitrate is noncorrosive
in presence of glass. It is used in military thermite grenades, in the manufacturing
process of barium oxide, in the vacuum tube industry, and in pyrotechnics for green fire. | [Appearance]

| Hazard Information | Back Directory | [Chemical Properties]
Barium nitrate is a stable, strong oxidizer. It is incompatible with combustible material,
reducing agents, acids, acid anhydrides, and moisture sensitive substance. It is haz-
ardous as magnesium plus barium oxide plus zinc, aluminum and magnesium alloys,
combustibles (paper, oil, wood), acids, and oxidizers. Mixtures with i nely divided
aluminum-magnesium alloys are easily ignitable and extremely sensitive to friction or
impact.
Barium nitrate on contact with combustible materials will ignite. Barium nitrate mixed
with aluminum powder, a formula for l ash powder is highly explosive. However, barium
nitrate is non-corrosive in the presence of glass. It is used in military thermite grenades, in
the manufacturing process of barium oxide, the vacuum tube industry, and for green i re
in pyrotechnics. | [General Description]
A white crystalline solid. Noncombustible, but accelerates burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided, an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen produced in fires. | [Reactivity Profile]
Mixtures of metal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures of nitrates with phosphorus, tin(II) chloride, or other reducing agents may react explosively [Bretherick 1979 p. 108-109]. | [Air & Water Reactions]
Soluble in water. | [Hazard]
Strong oxidizing agent. See barium.
| [Health Hazard]
Exposures to barium nitrate by ingestion or inhalation cause poisoning. The symptoms
include, but are not limited to, ringing of the ears, dizziness, irregular and elevated blood
pressure, blurred vision, irritation to the respiratory system, tightness of muscles (especially
in the face and neck), vomiting, diarrhea, abdominal pain, muscular tremors, anxiety, weak-
ness, labored breathing, cardiac irregularity, and convulsions. Poisoned workers also suffer
from kidney damage, cardiac or respiratory failure, tremors, convulsions, coma, and possi-
bly death. Prolonged periods of exposure to barium nitrate is known to cause damage of the
liver (anemia and possibly methemoglobinemia), spleen, kidney, bone marrow, and the CNS. | [Health Hazard]
Inhalation or contact with eyes or skin causes irritation. Ingestion causes excessive salivation, vomiting, colic, diarrhea, convulsive tremors, slow, hard pulse, elevated blood pressure. Hemorrhages may occur in the stomach, intestines, and kidneys. Muscular paralysis may follow. | [Potential Exposure]
Barium nitrate is used in making fireworks
(in green fire pyrotechnics), signal lights, ceramics;
and in the electronics industry; to make BaO2. Once used
in the vacuum tube industry. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and Wash immediately
with soap and Water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. See
also First Aid section in “Barium” entry. | [Shipping]
UN1446 Barium nitrate, Hazard Class: 5.1;
Labels: 5.1—Oxidizer, 6.1—Poisonous materials. | [Incompatibilities]
A strong oxidizer. Decomposes in
heat; may detonate if confined in elevating temperatures.
Keep away from strong acids; reducing agents. Contact
with organic and combustible materials (such as wood,
paper, oil and fuels); and aluminum magnesium alloys,
since violent reactions occur. Contact with sulfur powder
and finely divided metals can form shock-sensitive
compounds. | [Waste Disposal]
Dissolve waste in 6-MHCl.
Neutralize with NH4OH. Precipitate with excess sodium
carbonate. Filter, wash and dry precipitate and return to
supplier. | [Physical properties]
Barium nitrate has the molecular formula of Ba(NO3)2 and the molecular weight of 261.3745 g/mol. It is also known as “nitrobarite”. Its CAS number is 10022-31-8. It is soluble in water.
It can be prepared by a number of methods. The reaction between nitric acid and barium metal is one way and reaction with BaO or BaCO3 is another. Barium hydroxide and ammonium nitrate also form the product but ammonia is released as a by-product:
2HNO3 + Ba ---> Ba(NO3)2 +H2
2HNO3 + BaO ---> Ba(NO3)2 +H2O
Ba(OH)2 + 2NH4NO3 ---> Ba(NO3)2 + 2NH3 + 2H2O
Barium nitrate can also be prepared by the reaction of barium carbonate or barium carbonate with nitric acid:
BaCO3 + 2HNO3 ---> Ba(NO3)2 + CO2 +H2O
| [Uses]
Barium nitrate [Ba(NO3)2] burns with a bright green flame and is used in signal flares and
pyrotechnics. It can be produced by treating barium carbonate with nitric acid. | [Uses]
Barium nitrate is used in industry in
the production of green signal lights, to remove gases
from vacuum tubes, and in the production of barium
oxide. | [Uses]
manufacture of BaO2; pyrotechnics for green fire; green signal lights; in the vacuum-tube industry. | [Definition]
ChEBI: Barium nitrate is an inorganic nitrate salt of barium. It is an inorganic barium salt and an inorganic nitrate salt. | [Preparation]
Barium Nitrate can be prepared by a number of methods. The reaction
between nitric acid and barium metal is one way
and reaction with BaO or BaCO3 is another. Barium
hydroxide and ammonium nitrate also form the product
but ammonia is released as a by-product:
2HNO3＋ Ba→Ba(NO3)2＋H2
2HNO3＋ BaO→Ba(NO3)2＋H2O
Ba(OH)2＋ 2NH4NO3→Ba(NO3)2＋ 2NH3＋ 2H2O
Barium nitrate can also be prepared by the reaction of
barium carbonate or barium carbonate with nitric acid:
BaCO3＋ 2HNO3→Ba(NO3)2＋ CO2＋H2O
In this method, barium carbonate is suspended in
nitric acid. The solution is filtered and the product
crystallizes out. Alternatively, barium carbonate and
nitric acid are added to a saturated solution of
barium nitrate. The product is then obtained by crystallization.
Barium nitrate may also be prepared by adding
sodium nitrate to a saturated solution of barium
chloride. Barium nitrate precipitates out from the
solution. The precipitate is filtered, washed with
alcohol and dried. | [Flammability and Explosibility]
Nonflammable | [Purification Methods]
Crystallise it twice from water (4mL/g) and dry it overnight at 110o. It decomposes at higher temperatures to give mostly the oxide and the peroxide with only a little of the nitrite. POISONOUS. [Ehrlich in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 941 1963.] |
