Barium Sulfate
Barium sulfate (pronounced: BARE-ee-um SUL-fate) is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it.
Etymology
The term "barium" originates from the Greek word βαρύς (barys), meaning "heavy." The term "sulfate" is derived from the Latin word "sulfur," meaning "brimstone."
Description
Barium sulfate is used in medicine primarily as a contrast agent for radiographic examinations. It is ingested or administered by enema and shows up on X-rays to help healthcare professionals see the gastrointestinal tract more clearly.
