Barium nitrate Chemical Properties,Uses,Production

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.

Chemical Properties

Barium nitrate,Ba(N03)2 forms white crystals that are soluble in water at 20°C. It is formed by the reaction of barium carbonate or barium hydroxide with nitric acid.

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.

Chemical Properties

Barium Nitrate is a shiny, white crystalline solid.

Uses

manufacture of BaO2; pyrotechnics for green fire; green signal lights; in the vacuum-tube industry.

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.

Air & Water Reactions

Soluble in water.

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].

Hazard

Strong oxidizing agent. See barium.

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.

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.

Safety Profile

A poison by ingestion, subcutaneous, parenteral, and intravenous routes. An irritant to slun and eyes. When heated to decomposition it emits very toxic fumes of NO,. An oxiduer. Mixtures with finely divided aluminum-magnesium alloys are easily ignitable and extremely sensitive to friction or impact. Such mixtures are used in chemical photoflash applications. Incompatible with (Mg + BaO2 + Zn), Al, and Mg alloys. When heated to decomposition it emits toxic fumes of NO,. See also BARIUM COMPOUNDS (soluble) and NITRATES.

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.

storage

Barium nitrate should be kept stored in a tightly closed container, in a cool, dry, venti- lated area, protected against physical damage. It should be separated from heat, sources of ignition, incompatible substances, combustibles, and organic or other readily oxidizable materials. Barium nitrate should not be stored on wood l oors or with food and beverages

Shipping

UN1446 Barium nitrate, Hazard Class: 5.1; Labels: 5.1—Oxidizer, 6.1—Poisonous materials.

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.]

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.

Precautions

After accidental exposures to barium nitrate by ingestion, swallow, or inhalation, workers should induce vomiting immediately as directed by medical personnel. Never give any- thing by mouth to an unconscious person. Get medical attention immediately
