Product Description
Uses:
Barium sulfate (BaSO4), as mentioned, is used in medicine as an opaque liquid medium to block X-rays when ingested, thus providing an image of ulcers and intestinal problems. It is also used in the manufacture of paints, rubber, and plastics.
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, known as “l(fā)ithopone”. Similarly, in combination with sodium sulfide, it is used to produce fine pigment particles of uniform size, known as “blanc fixe”. Natural barite, however, has greater commercial application than the precipitated salt. 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.
Barium sulfate is frequently used clinically as a contrast agent for X-ray imaging and other diagnostic procedures. It is most often used in imaging of the gastrointestinal tract. It is administered, orally or by enema, as a suspension of fine particles in an aqueous solution. Although barium, 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 prior compounds, which it replaced. Its absorbance of Xrays 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. One major manufacturer of artists’ oil paint sells “permanent white” that contains a mixture of titanium white pigment and barium sulfate. Barium sulfate itself is called blanc fixe (French for “permanent white”).
range. It is applied by spray painting to almost any substrate (metals, plastics, glass) for use in integrating spheres, laser cavities, lamp reflectors and display backlights. It is characterized by a near-perfect Lambertian (i.e. diffuse) reflectance of up to 98% in the spectral range from 250 to 2500 nm.
Other chemical applications of barium sulfate are used as a pigment for photographic paper. It is also used to prepare many other barium salts. It is available in many forms commercially.
A heavy, white powder made by treating barium salts with sulfuric acid. Barium sulfate was used as a preliminary coating for raw photographic papers to produce a smooth, white surface and to act as a barrier to prevent reactions between the paper and subsequent coatings of gelatin or collodion emulsions. Barium sulfate was also added directly to emulsions to produce a matte finish. It is also known as barite, synthetic barite, blanc fix, baryta white, and mountain snow.
barium sulfate is an emulsion stabilizer for sunscreen formulations. outside of sunscreen preparations, this inorganic salt is most commonly used in non-cosmetic soaps.
