Barium sulfate - The Full Wiki

Barium sulfate is a white crystalline solid with the chemical formula BaSO 4.It is insoluble in water and other traditional solvents but is soluble in concentrated sulfuric acid.The mineral barite is composed largely of barium sulfate and is a common ore of barium.It is often extracted in a blast furnace, as it can cope with high temperatures.

Barium oxide - Simple English Wikipedia, the free encyclopedia

Properties. Barium oxide is a white solid. It dissolves in water to make barium hydroxide.It reacts with acids to make barium salts.. Preparation. Barium oxide is made by heating barium carbonate with carbon.This prevents barium peroxide from forming when it is heated. It can also be made by heating barium nitrate.. Uses. Barium oxide can be added to glass instead of lead(II) oxide.

Barium sulfate is also readily removed from the body, unlike prior compounds, which it replaced. Its absorbance of X-rays is also higher. Barium sulfate mixtures are used as white pigment for paints. In oil paint, barium sulfate is almost transparent, and is used as a filler or to modify consistency.

Barium enema | Health Encyclopedia

The tube is connected to a bag that holds a liquid containing barium sulfate. This is a contrast material that highlights specific areas in the colon, creating a clear image. The barium flows into your colon. X-rays are taken. A small balloon at the tip of the enema tube may be inflated to help keep the barium inside your colon.

barium

Barium (Ba) is a soft, silvery-white metallic element that readily tarnishes in air. It is one of the alkaline earth metals.It was discovered by Humphry Davy in 1808 and occurs chiefly as barite (barium sulfate, BaSO 4) and as witherite (barium carbonate, BaCO 3).. The compounds of barium resemble those of calcium but are poisonous.
