It combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds, which are used by the oil and gas industries to make drilling muds.
Barium compounds mostly impact the environment as a result of industrial waste water.
of BaO2 is formed by reaction of barium salt solution and hydrogen peroxide solution BaO2 crystallizes as grayish white transparent tetragonal crystals which are isomorphous with barium sulfate, which also gives a vivid green color, as do all barium compounds. White or gray powder microstrip, in the air to absorb carbon dioxide emits oxygen generation barium carbonate, with the formation of acid salt and hydrogen peroxide.
