Barium Sulfate

Barium sulfate

CAS NO.:7727-43-7

Barium sulfate, also known as barium white, is a white crystalline solid with the chemical formula BaSO4. It is almost insoluble in water and other traditional solvents, but soluble in concentrated sulfuric acid. Barite is the main component of barite, which is a common barium ore. Barium sulfate is a common laboratory and industrial chemical.

Application

Barium sulfate has many commercial applications. It is used either as natural barite, or precipitated BaSO4.

The precipitated salt in combination with equimolar amount of co-precipitated zinc sulfide formerly was used as a white protective

coating pigment. It is used as an additive in drilling mud in crude oil, well drilled to lubricate and cool the drilling bit, and to plaster

the walls of the drill hole to prevent caving. It is used as a filler in automotive paints, plastics and rubber products.

It also is used as a filler in polyurethane foam floor mats, white sidewall rubber tires and as a flux and additive to glass to

increase the refractive index. Medically used as the agent (barium meal) for X-rays on the gut and stomach. Barium sulfate is

the only non-toxic barium salts. It can be used in analysis reagents, electronics, instrumentation, metallurgy and other industries.

It can also be used as a white pigment and an administrated agent upon stomach X-ray angiography; it can also used as copper

flux, drilling mud weight enlarging agent and the filling agent of rubber, paper, and plastic.
