10-08-2010· Barium sulfate is a chemical compound composed of barium and sulfate ions. It contains barium in the +2 oxidation state, as in all barium compounds. It does not dissolve in water. If it did, it would be very toxic. It is used in X-rays of the stomach and intestines to see whether there is a problem with them. Its chemical formula is BaSO 4. Related pages.

Barium sulfate BaSO4 PubChem

Barium sulfate is a heavy metal with a high atomic number (Z=56) and a K shell binding energy (K-edge of 37.4 keV) very close to that of most diagnostic x-ray beams. Due to these characteristics, barium is an ideal medium for the absorption of x-rays [FDA label]. Barium sulfate is essentially not absorbed from the GI tract nor metabolized in the body.
