Barium has 40 isotopes. 7 of them are naturally occurring, 6 of which are stable. Barite, or barium sulfate (BaSO4), when ground is used as a filler for rubber, plastics, and resins. It is insoluble in water and so is used in X-rays of the digestive system. Barium nitrate, Ba(NO3)2, burns brilliant green. Naturally occurring barium (56 Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001.

barium

(Ba) [bar´e-um] barium test x-ray examination using a barium mixture to help locate disorders in the esophagus, stomach, duodenum, and small and large intestines. Such conditions as peptic ulcer, benign or malignant tumors, colitis, or enlargement of organs that might be causing pressure on the stomach may be readily identified with the use of barium tests. If perforation exists or is suspected, the barium test should not be administered. It is important to evacuate the barium completely following the study; a mild laxative is usually prescribed for this purpose.
Barium sulfate is a harmless chalky, water-insoluble compound that does not permit x-rays to pass through it. Taken before or during an examination, it causes the intestinal tract to stand out in silhouette when viewed through a fluoroscope or seen on an x-ray film.
Two main types of tests are conducted with the use of barium: the barium meal or barium swallow, for radiologic examination of the upper gastrointestinal tract, and the barium enema for examination of the lower gastrointestinal tract.

barium

Chemistry
A silver-white alkaline earth-metallic element—atomic number 56, atomic weight 137.3—which melts at 727ºC. Pure barium does not exist in nature as it is oxidised, often as baryta.
Imaging
Barium is the core constituent in non-radioactive radiocontrast studies (e.g., barium enema, barium swallow), and formulated as a chalky liquid, popularly, a milkshake.

About Barium

Barium is a soft light silver metal which belongs to the group of the alkaline earth metals. It is quite reactive and easily reacts with air and water, as well as forms alloys and other chemical compounds. The name of barium comes from a Greek word meaning heavy. It is impossible to find this element in its pure form on our planet, and it is extracted from various minerals and chemical compounds. This element does not exist in the most of biological living organisms, and in its pure form it is quite toxic. Industrial uses of barium include producing various vacuum or cathode tubes, wires, etc. This element found application in producing pigmentation agents and X-ray technology equipment.

Uses of Barium

Barium, a soft, silvery metallic element with the symbol Ba, was mostly used in vacuum tubes, like TV picture tubes. Barium is especially used in alloys with aluminium, nickel, steel, iron, calcium, silicon and manganese. Barium nitrate, an alloy with the formula Ba(NO3)2, can be used in fireworks. Barium sulfate, a compound with the formula BaSO4, is employed in the petroleum industry, as well as in glassmaking, paints, rubbers, plastics, ink, and varnishes. Barium carbonate (BaCO3) is exploited in the manufacture of specialty glass, or in ceramics. The applications of Barium chloride (BaCl2) include laboratories and heat-treating baths.

Compounds with Barium

• BaCO₃: Barium carbonate
• BaSO₄: Barium sulfate
