Chemistry & industry
Pharmacology
Metabolism/Metabolites
Barium compounds are absorbed via ingestion and inhalation, the extent of which depends on the individual compound. In the body, the majority of the barium is found in the bone, while small amounts exists in the muscle, adipose, skin, and connective tissue. Barium is not metabolized in the body, but it may be transported or incorporated into complexes or tissues. Barium is excreted in the urine and faeces. (L214)
Uses & manufacturing
General Manufacturing InformationBarium azide (Ba(N3)2): ACTIVE
Applications
DescriptionBarium 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.
UsesHigh explosives.
General DescriptionA 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.
Preparation methods
PreparationBarium 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.
