Catalog Number
ACMA00014284
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.
