Barium sulfate BaSO

Barite [13462-86-7], natural barium sulfate, BaSO, commonly known as barytes, and sometimes as heavy spar, tiU, or cawk, occurs in many geological environments in sedimentary, igneous, and metamorphic rocks. Commercial deposits are of three types vein and cavity filling deposits residual deposits and bedded deposits. Most commercial sources are replacement deposits in limestone, dolomitic sandstone, and shales, or residual deposits caused by differential weathering that result in lumps of barite enclosed in clay. Barite is widely distributed and has minable deposits in many countries. [Pg.475]

Barium sulfate (BaSO ), 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. [Pg.81]

Barium. The metal "barium has no significant use. Its principal compounds arc barium sulfate, BaSO, which is only very slightly soluble in water and dilute acids, and barium chloride, BaCl2 2H20, which is soluble in water. [Pg.193]

Suppose we add one gram of solid barium sulfate, BaSO, to 1.0 liter of water at 25°C and stir until the solution is saturated. Very little BaSO dissolves. Careful measurements of conductivity show that one liter of a saturated solution of barium sulfate contains only 0.0025 gram of BaSO, no matter how much more BaSO is added. The BaSO that does dissolve is completely dissociated into its constituent ions. [Pg.823]

Other scales, such as calcium sulfate (CaSO and barium sulfate (BaSO ) are only slightly soluble in acid. Both are soluble in complexing agents such as EDTA and other carboxylic acid-type chelating agents. Barite can be very hard and thus chemically impenetrable, or it can be fine and soft, thereby enabling mechanical removal or partial chemical removal. Barite sometimes occurs in mixed-scale deposits, wherein an acid-soluble portion (e.g., calcium carbonate) can be removed, along with subsequent physical removal of the barite portion. [Pg.190]
