BARIUM AZIDE Chemical Properties,Usage,Production
Barium azide is a flammable, crystalline solid which can be used or transported in solution.
Colorless monoclinic crystal; density 2.936 g/cm3; decomposes at 120°C; soluble in water, slightly soluble in ethanol.
Barium azide may be prepared by reacting sodium azide with a soluble barium salt. The solution is concentrated to allow crystals grow. Crystals will explode if fully dried, or subject to friction. Product should be stored damp with ethanol.
A slurry of white crystals. When dry, a high explosive that easily ignited and quick to burn vigorously. Wetting reduces sensitivity to shock and heat. Generates toxic oxides of nitrogen when burned.
Air & Water Reactions
Highly flammable. Soluble in water.
BARIUM AZIDE is a suspension or slurry of of an unstable solid in sufficient water to allow safe shipping and handling. May explode if allowed to dry out and then heated or shocked. Incompatible with strong oxidizing agents, strong reducing agents.
Explodes when shocked or heated.
Some are toxic and may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
A poison. Moderate explosion hazard when shocked or heated to 275'. Spontaneously flammable in air. Very unstable. When heated to decomposition it emits toxic fumes of NO,. See also BARIUM COWOUNDS (soluble) and AZIDES.
Barium Azide is used in high explosives.
