Barium is a chemical element; it has symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. The most common minerals of barium are barite (barium sulfate, BaSO 4) and witherite (barium carbonate ...
Barium is used in vacuum tubes as a getter to remove gases. [61] Barium sulfate has many uses in the petroleum industry, [4] [81] and other industries. [4] [61] [82] Radium has many former applications based on its radioactivity, but its use is no longer common because of the adverse health effects and long half-life.
Baryte, barite or barytes (/ ˈ b ær aɪ t, ˈ b ɛər-/ BARR-eyet, BAIR-[7] or / b ə ˈ r aɪ t iː z / bə-RYTE-eez [8]) is a mineral consisting of barium sulfate (BaS O 4). [3] Baryte is generally white or colorless, and is the main source of the element barium.
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water . It occurs in nature as the mineral barite , which is the main commercial source of barium and materials prepared from it.
