BARIUM AZIDE Chemical Properties,Usage,Production

Chemical Properties

Barium azide is a flammable, crystalline solid which can be used or transported in solution.

Physical properties

Colorless monoclinic crystal; density 2.936 g/cm3; decomposes at 120°C; soluble in water, slightly soluble in ethanol.

Uses

High explosives.

Preparation

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.

General Description

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.

Reactivity Profile

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.

Hazard

Explodes when shocked or heated.

Health Hazard

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.

Safety Profile

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.

Potential Exposure

Barium Azide is used in high explosives.

Shipping

UN1571 Barium azide wetted with not ,50% water, by mass, Hazard Class: 4.1; Labels: 4.1—Flammable solid, 6.1—Poisonous materials. UN0224 Barium Azide dry or wetted with ,50% water, by mass, Hazard Class: 1.1A; Labels: 1.1A—Explosive (with a mass explosion hazard); A—Substances which are expected to mass detonate very soon after fire reaches them. Packing Group 1.

Incompatibilities

Carbon disulfide. It can explode when heated or shocked.
