Barium nitrate, with the chemical formula Ba(NO₃)₂, is a white, crystalline solid that is soluble in water. It is primarily used in pyrotechnics to produce green-colored flames in fireworks. This compound is also employed in the manufacturing of barium oxide, which is essential for the production of specialty glass and ceramics. Barium nitrate's ability to absorb moisture from the atmosphere makes it useful in vacuum tube technology and in the preparation of barium-containing chemicals. In the past, it was utilized in the production of barium peroxide, which has oxidizing properties useful in various industrial processes. However, due to its toxicity, particularly when inhaled or ingested, strict safety precautions must be observed during handling and use. Barium nitrate remains valuable in niche industrial applications where its specific properties are required.
