Barium Carbonate

Name: Barium Carbonate, Barium monocarbonate, Carbonic acid barium salt
Chemical formula: BaCO3
Particle size: very fine powder

Description: Barium carbonate is used both in 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 white light. Barium carbonate is convenient to use in chlorate based color compositions since it will neutralize residual acid which reduces the risk of spontaneous ignition
