barium ag mill

Barium - Wikipedia. Barium is a chemical element with 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.Its hydroxide, known in pre-modern times as baryta, does not occur as a mineral, but can be prepared by heating barium carbonate.
