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.
