Air and Water Reactions:No rapid reaction with air No rapid reaction with water
Reactive Group:Salts, Acidic
Reactivity Profile:BORON OXIDE is non-combustible. Of generally low chemical reactivity. Reacts exothermically but slowly with water to form boric acid, a weak acid. Reacts exothermically with strong bases. May react with strong reducing agents such as metal hydrides, metal alkyls to generate flammable or explosive gases. May react violently on contact with bromine pentafluoride. Corrosive to metals in the presence of air.
Ionization Potential:13.50 eV
Flammable Limits:Noncombustible Solid
Corrosivity:Very corrosive to metals in the presence of oxygen
