Barium Nitrate POWDER [Ba(NO3)2] white fine powder. Milled 325
mesh.
Not very strong green effect. Used with aluminum powder to
produce silver effects. Below 1000C aluminum burns silvery-gold, characteristic
of aluminum-gunpowder compositions. Above 1000C it burns silver, and may be
achieved using barium nitrate. Boric acid should always be used in compositions
containing barium nitrate and aluminum. Barium nitrate is used as an oxidizer in
both white and green color compositions. When chlorine donors are present in a
composition a green color will result from the formation of BaCl+ in the flame.
Without chlorine donors BaO will be formed which emits bright white light.
Barium nitrate is seldom used as the sole oxidizer in green color compositions.
It is usually combined with perchlorates to improve the color and increase the
burning rate. A poor green effect as a coloring agent by itself. Boric acid
often used with compositions with Al. Sometimes used in flash compositions.
Barium nitrate is poisonous and a dust mask should be worn at all times when
handling it. Mixtures of metal powders and barium nitrate sometimes heat up
spontaneously and may ignite, especially when moist. This can usually be
prevented by the addition of small amounts of boric acid (1 to 2%). It is
advisable to avoid using water to bind such compositions. Red gum or shellac
with alcohol or nitrocellulose lacquer are preferred binder and solvents
