Description and Uses
Barium nitrate is a stable, strong oxidiser. It is incompatible with combustible material, reducing agents, acids, acid anhydrides, and moisture-sensitive substance. Barium nitrate is poisonous, is a respiratory irritant, and is hazardous if mixed with flammable materials. Barium oxide plus zinc, aluminium and magnesium alloys are combustibles (paper, oil, wood), acids, and oxidisers and is hazardous. Mixtures with finely divided aluminium–magnesium alloys are easily ignitable and extremely sensitive to friction or impact. Barium nitrate mixed with aluminium powder, a formula for flash powder, is highly explosive. However, barium nitrate is noncorrosive in presence of glass. It is used in military thermite grenades, in the manufacturing process of barium oxide, in the vacuum tube industry, and in pyrotechnics for green flame.
manufacture of BaO2; pyrotechnics for green fire; green signal lights; in the vacuum-tube industry.
