Barium sulfate is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs in nature as the mineral barite, which is the main commercial source of barium and materials prepared from it. Its opaque white appearance and its high density are exploited in its main applications.

Functions of Barium Sulfate
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 Label.
Barium sulfate is essentially not absorbed from the GI tract nor metabolized in the body. Barium sulfate is used to fill the gastrointestinal tract lumen or to coat the mucosal surface and is administered orally, rectally, or instilled into an enterostomy tube or catheter.
Barium sulfate enhances delineation of the GI tract. The barium suspension covers the mucosal surface of the GI tract, allowing its shape, distensibility, motion, integrity, continuity, location within the torso, relationship to other organs to be closely examined. Various abnormalities, such as benign or malignant tumors, ulcers, strictures, diverticula, inflammation or infection, altered motility, displacement and other pathology can thereby be identified.
Physical Properties
Pure barium sulfate is found as a white, odorless powder or small crystals with a density of 4.49 g/mL, a melting point of 1580 °C and a boiling point of 1600 °C.
Chemical Properties
Barium sulfate is said to have extremely poor solubility in the universal solvent water. It is also insoluble in alcohols, and soluble in concentrated acids. It reacts violently with aluminum powder. Barium sulfate has numerous medical and radio imaging uses due to its water insolubility and radio-opaque properties.
Usage of Barium Sulfate
Medical Imaging (Barium Sulfate Suspension): Barium sulfate is widely used in medical radiology for imaging the digestive system. A suspension of barium sulfate is ingested by the patient before X-ray examinations of the gastrointestinal tract. The high atomic number of barium enhances the contrast in X-ray images, allowing for better visualization of the digestive organs.
Barium sulfate is used as a weighting agent in drilling fluids in the oil and gas industry: It helps control the pressure in the wellbore and prevents blowouts during drilling operations.
Paints and Coatings: Barium sulfate is used as a filler or extender in the production of paints and coatings. It improves the durability and brightness of the finished products.
Plastics and Rubber Industries: It is employed as a filler in the production of plastics and rubber to enhance their properties.
Paper Industry: Barium sulfate is used in the paper industry as a coating pigment to improve the brightness and smoothness of paper.
Electronics: In the electronics industry, barium sulfate is used as a component in the manufacture of certain electronic components.
Photography: Barium sulfate has been historically used in some photographic papers and films.
Storage & Handling
· Storage: Store in a cool, dry, and well-ventilated place. Keep away from moisture during transportation.
· Handling: The product is safe, but avoid inhaling dust. If skin contact occurs, wash thoroughly with soap and water.
