Uses
Radiocontrast agent Barium sulfate is frequently used clinically as a radiocontrast agent for X-ray imaging and other diagnostic procedures. It is most often used in imaging of the GI tract during what is colloquially known as a 'Barium meal'. Radiocontrast agents (or simply contrast agents) are compounds used to improve the visibility of internal bodily structures in an X-ray image. ...
In the NATO phonetic alphabet, X-ray represents the letter X. An X-ray picture (radiograph) taken by Röntgen An X-ray is a form of electromagnetic radiation with a wavelength approximately in the range of 5 pm to 10 nanometers (corresponding to frequencies in the range 30 PHz...

The gastrointestinal tract (GI tract), also called the digestive tract, alimentary canal, or gut, is the system of organs within multicellular animals that takes in food, digests it to extract energy and nutrients, and expels the remaining waste. ...
Preprepared Barium Sulfate suspension for oral consumption A barium meal is a procedure in which barium sulfate is ingested by a patient and, in conjunction with X-rays, images depicting the digestive system: the distal esophagus, stomach and duodenum, are obtained. ...
It is administered, orally or by enema, as a suspension of fine particles in an aqueous solution (often with sweetening agents added). Although barium is a heavy metal, and its water soluble compounds are often highly toxic, the extremely low solubility of barium sulfate protects the patient from absorbing harmful amounts of the metal. Barium sulfate is also readily removed from the body, unlike Thorotrast, which it replaced. The compound works due to barium's relatively high atomic number (Z = 56), since large nuclei absorb X-rays much better than smaller nuclei. This 2qt (about 2 liters) enema bag, or fountain syringe, equipped with a rectal nozzle, is to be filled with water or a solution, then suspended near the patient using the hook. ...
A heavy metal is any of a number of higher atomic weight elements, which has the properties of a metallic substance at room temperature. ...
Thorotrast is a suspension containing particles of the radioactive compound thorium dioxide, ThO2, used as a contrast medium in X-ray diagnostics in the 1930s and 40s (use in some countries, such as the U.S. continued into the 1950s). ...

Pigment Barium sulfate mixtures are used as white pigment for paints, when combined with zinc sulfide (ZnS) it is called lithopone, when combined with sodium sulfate (Na2SO4) it is called blanc fixe although blance fixe is also the name given to pure precipitated barium sulphate. It replaced white lead due to the latter's toxicity. Zinc sulfide (or zinc sulphide) is a chemical compound with the formula ZnS. Zinc sulfide is a white to yellow colored powder or crystal. ...

Pyrotechnics Barium sulfate is also used as a high temperature oxidizer in certain pyrotechnic formulas, as it produces a green colored light while it burns. Barium nitrate is more common in green pyrotechnic formulas, as it is a more amiable oxidizer while still producing green colored light.
Other uses Barium sulfate is used as a filler in plastics and as a component of oil well drilling fluid to increase the density. An oil well is a term for any perforation through the Earths surface designed to find and release both petroleum oil and gas hydrocarbons. ...
It is used in brake linings, acoustic foams and powder coatings
Barium sulfate is also used during the procedure of the soil pH test. In this test it is used so that it precipitates out any particles (usually clay particles) which would otherwise 'cloud' solution preventing one from seeing the colour of the pH indicator i.e. the result of the test. Soil pH is an indication of the alkalinity or acidity of soil. ...
It is used in root canal filling.
History Barium sulfate is reduced to barium sulfide by carbon. The accidental discovery of this conversion many centuries ago led to the discovery of the first synthetic phosphor.[1] The sulfide, unlike the sulfate, is water soluble. Barium sulfide is the chemical compound with the formula BaS. This material was once known as Bologna Stone, the first synthetic phosphor. ...
A phosphor is a substance that can exhibit the phenomenon of fluorescence (glowing during absorption of radiation of another kind) or phosphorescence (sustained glowing without further stimulus). ...
