Product Name
Barium Nitrate
Description
Barium nitrate appears as a white crystalline solid. Noncombustible, but accelerates burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided, an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen produced in fires.;DryPowder; OtherSolid; PelletsLargeCrystals;COLOURLESS-TO-WHITE CRYSTALS OR CRYSTALLINE POWDER.;White, odorless solid.

Application
Barium nitrate serves several important functions across different industries due to its properties as a stable and strong oxidizer. Primarily, it is utilized in the production of barium oxide and is a key component in the vacuum tube industry. In the field of pyrotechnics, barium nitrate is valued for its ability to produce vibrant green flames, which makes it an essential ingredient in fireworks and green signal lights. Additionally, it is used in military applications, such as in thermite grenades. Despite its utility, care must be taken when handling barium nitrate, as it is a hazardous substance. It is poisonous and can irritate the respiratory system. Furthermore, when mixed with aluminum powder or other finely divided metals, it becomes highly sensitive to ignition from friction or impact, forming explosive mixtures. Therefore, it is crucial to keep barium nitrate away from combustible materials, reducing agents, and acids to prevent dangerous reactions.
