Boric Acid [H3BO3] White powder.
Boric acid is a white powder which is used as an additive to
compositions containing aluminum or magnesium and a nitrate. The metal powder
can reduce the nitrate to an amide, which will react with the metal powder in a
very exothermic reaction that can lead to spontaneous ignition of the
composition. This process is often accompanied by a smell of ammonia and is most
likely to occur with wet compositions. Addition of a few percent boric acid can
often prevent this reaction from taking place since it neutralizes the very
basic amides forming ammonia and a borate. It is also advisable to avoid using a
water-soluble binder for these compositions. Using red gum or shellac with
alcohol or nitrocellulose lacquer is safer.
Boric acid is not particularly toxic or dangerous.
