Barium sulfate

Description:
Barium sulfate (BaSO₄) is an inorganic compound characterized by its white crystalline solid form, which is odorless and insoluble in water. It is primarily used in various industrial applications, including as a contrast agent in medical imaging, particularly in X-ray imaging of the gastrointestinal tract. Barium sulfate is known for its high density and radiopacity, making it effective for enhancing the visibility of internal structures. Chemically, it is a sulfate salt composed of barium cations and sulfate anions, exhibiting a high degree of stability and non-reactivity under normal conditions. Its melting point is quite high, and it does not decompose easily, which contributes to its utility in various applications. Additionally, barium sulfate is utilized in the production of paints, plastics, and rubber, serving as a filler and pigment. While generally considered safe in its applications, precautions are necessary when handling it in powdered form due to potential inhalation risks. Overall, barium sulfate is a versatile compound with significant importance in both medical and industrial fields.
