Barium oxalate is a chemical compound with the chemical formula BaC₂O₄. It is a barium salt of oxalic acid. It consists of barium cations Ba²⁺ and oxalate anions C₂O2−4. It is a white odorless powder that is sometimes used as a green pyrotechnic colorant generally in specialized pyrotechnic compositions containing magnesium metal powder. Flame color is rich and vivid without additional chlorine donors. Such compositions burn rate is satisfied without commonly used oxidizers as nitrates, chlorates and perchlorates.
