Detailed Product Description:
Barium sulfate (or barium sulphate) is a fine white powder. It is poorly
soluble 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.
This is ACS Reagent Grade material with 97.5% minimum purity. This
grade is intended for high purity commercial and industrial applications and
unlike the similar purity “USP Grade” is not intended for internal or medicinal
Barium sulfate is commonly used as a filler in plastics and adhesives and
as a component of oil well drilling fluid to increase the density. It is used
in brake linings, anechoic foams and powder coatings.
Barium sulfate mixtures are used as white pigments for paints. The combination
of barium sulfate and zinc sulfide (ZnS) is called lithopone. Barium sulfate
itself is called blanc fixe. It replaced white lead due to the latter's toxicity.
Barium sulfate is also used as a high temperature oxidizer in certain pyrotechnic
formulas, as barium compounds emit a green colored light when burned. Barium
nitrate is more common in green pyrotechnic formulas, as it contains an oxidizer
while still producing green colored light.
In its USP Grade, Barium sulfate is frequently used clinically as a radio-contrast
agent for X-ray imaging and other diagnostic procedures. It is most often used
in imaging of the GI tract during what is colloquially known as a “Barium meal.”
It is administered, orally or by enema, as a suspension of fine particles in an
aqueous solution (often with sweetening agents added). Although barium is a
heavy metal, and its water-soluble compounds are often highly toxic, the extremely
low solubility of barium sulfate protects the patient from absorbing harmful amounts
of the metal. Barium sulfate is also readily removed from the body, unlike Thorotrast
which it replaced. Due to the relatively high atomic number (Z = 56) of barium, its
compounds absorb X-rays more strongly than compounds derived from lighter nuclei.
