Barium is a metal, but has no significant uses as such. A significant medical use of barium is to enhance x-ray images of the intestinal tract. Barium has a high atomic number and absorbs x-rays strongly. A thin paste of barium sulfate, BaSO 4, and water is is swallowed to coat the alimentary canal.This gives greater definition and contrast to the x-ray images of the tract.The low solubility of barium sulfate minimizes the toxic effects which might occur with other barium compounds.The mineral form of barium sulfate is called barite.his gives greater definition and contrast to the x-ray images of the tract.
