The metal is used as a “getter” in vacuum tubes. Barite is extensively used as a weighing agent in oil well drilling fluids, and is used in making rubber. All barium compounds that are water or acid soluble are poisonous. Naturally occurring barium is a mixture of seven stable isotopes. Twenty two other radioactive isotopes are known to exist.
