Not hygroscopic. The hygroscopic point corresponds to 99% humidity. t PL 592 °C. Begins to decompose above t PL 203,5 Heat of fusion kJ/kg. Heat of formation -992,7 kJ/mol. Heat capacity at 300K 570 j / (kg·K), thermal conductivity 0.63 W/(m·K). Density of 3.24 g / cm3.
Toxic. MPC in terms of barium 0.5 mg / m3. Dust in the eyes is not desirable. Irritating to mucous membranes. In recent years, the United States is seeking to replace barium nitrate with less toxic oxidants, such as potassium nitrate or strontium nitrate.
Barium nitrate (Barium dinitrate; Nitric acid) is used for the manufacture of barium oxide, barium peroxide, optical glass, ceramics, as an accelerator of the burning rate, for green fireworks, signal flashes, tracer bullets, as a preservative, as a chemical reagent, for medicine and heat treatment of metals, etc.
Application of barium nitrate in pyrotechnics: compositions on barium nitrate burn slower than on potassium nitrate and ignite worse. It is used in pyrotechnic compositions of green fire (together with chlorine donors), as well as in lighting, thermite-incendiary and flammable. Without chlorine donors, compositions based on barium nitrate burn with a white flame with a greenish-yellow tint.
