Barium nitrate
Barium nitrate is an inorganic salt with formula Ba(NO₃)₂. It is used as an oxidizer in pyrotechnics and as a feedstock for other barium compounds.
Oxidizing agent: A substance that accepts electrons from another substance in a redox reaction. Barium nitrate supplies oxygen-containing nitrate ions that support combustion.
Green fire: A flame emission perceived as green because excited atoms or ions emit green wavelengths. Barium compounds produce characteristic green emissions in pyrotechnic flames.
Barium: A soft, silvery alkaline-earth metal with atomic number 56. Barium forms the Ba²⁺ ions that pair with nitrate in this salt.
Barium poisoning: Illness caused by exposure to bioavailable barium compounds, which can disrupt nerve and muscle function. Soluble barium ions released from ingestion can cause severe systemic toxicity.
Nitrate: A polyatomic ion, NO₃⁻, containing one nitrogen atom bonded to three oxygen atoms. Nitrate ions account for the salt’s oxidizing behavior when heated.
Pyrotechnics: The design and use of compositions that produce controlled light, color, sound, or smoke. Barium nitrate serves as an oxidizer in some pyrotechnic mixtures.
Ionic compound: A substance whose ions are held together by electrostatic attraction in an extended solid structure. Barium nitrate is an ionic lattice of barium and nitrate ions.
Chemical hazard: A property of a substance that can cause harm through exposure or unsafe handling. Barium nitrate combines toxic barium content with oxidizer-related fire hazards.
Thermal decomposition: The breakdown of a chemical compound caused by heat. Heating barium nitrate releases oxygen and forms barium oxide.
Barium carbonate: An inorganic compound with formula BaCO₃, used in ceramics, glass, and chemical manufacture. It is among the barium compounds made using barium nitrate as a starting material.
