Barium sulfate (BaSO4), or barite, is the most common mineral abundant in barium. This mineral has a density of 4.5g/cm3 and is extremely insoluble in water. Uses of barium sulfate include being a radiocontrast agent for X-ray imaging of the digestive system. Barium carbonate (BaCO3) is also commonly used as a rat poison.
Barium compounds (which are toxic) are also useful in pyrotechnic devices where they impart a characteristic green color.
