바륨 아지드 C화학적 특성, 용도, 생산
개요
Barium azide, is a crystalline solid with not less than 50% water by mass that explodes when shocked or heated. Barium azide decomposes and gives off nitrogen at 240°F (115.5°C) and is soluble in water. The four-digit UN identification number for barium azide is 1571. Its primary use is in high explosives.
화학적 성질
Barium azide is a flammable, crystalline solid
which can be used or transported in solution.
물리적 성질
Colorless monoclinic crystal; density 2.936 g/cm
3; decomposes at 120°C; soluble in water, slightly soluble in ethanol.
용도
High explosives.
제조 방법
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.
일반 설명
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.
공기와 물의 반응
Highly flammable. Soluble in water.
반응 프로필
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.
위험도
Explodes when shocked or heated.
건강위험
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.
잠재적 노출
Barium Azide is used in high
explosives.
