説明
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.

化学的特性
Barium azide is a flammable, crystalline solid
which can be used or transported in solution.
-
物理的性質
Colorless monoclinic crystal; density 2.936 g/cm3; decomposes at 120°C; soluble in water, slightly soluble in ethanol.
-
使用
High explosives.
-
製造方法
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.
-
一般的な説明
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.
