Named from the Greek word meaning "heavy," barium is a soft, silvery-white metal. It is an active metal, reacting with air, water, acids and bases. Because it is insoluble in the body, barium sulfate is used as an x-ray tracer for the stomach and intestines. Barium is also used in drilling fluids for oil exploration, as well as in paints ...Web

The major ore of barium that are widely used for the extraction of barium is barite. Physical properties. Pure barium is a silvery-white shiny malleable metal.

Barium sulfate (BaSO 4) content is used to evaluate the grade of barite ore. In the present study, we report a method to determine the BaSO 4 content in barite ore by phase conversion-headspace gas chromatography with partial pressure correction. In this method, the ore sample is roasted with sodium carbonate and potassium carbonate after ...Web

On the other hand, attempts were done to prepare barium hexaferrite from the Baharia iron ore and the west barite with and without coke, and comparing its magnetic properties with that prepared from pure hematite and barium oxide. Also, the catalytic activity for all specimens towards H 2 O 2 decomposition were studied. 2.Web

Introduction. The average content of barium (Ba) in Chinese coal and world coal is 159 and 150 μg/g, respectively [1], [2].Zhou et al. [3] reported a high content of Ba, 10,605 μg/g, in a core coal sample from the Xiheishan exploration area, Junggar Basin, Xinjiang Province, China; however, only one out of 32 samples contains high Ba, and the …Web

Where is Barium found. The primary sources of the element are barite and witherite found in several ore deposits. It can also be produced in the laboratory by heating barium oxide with aluminum powder, and also through electrolysis of molten barium chloride [1].Web
