The barium swallow study, also known as a barium esophagogram or esophagram, is a contrast-enhanced radiographic study commonly used to assess structural characteristics, and to some extent the functional characteristics of the esophagus. [1] It is important to distinguish this from a "modified barium swallow" study or a "videofluoroscopic …
Montana, Nevada, and Tennessee. In 2010, 670 thousand tons of barite, a natural barium sulfate ore, were mined in the US, most of it in Nevada. By 2010, 95% of barite sold in US was used as a weighting agent in natural gas and oil field drilling (USGS, 2011). Although it is also used in making a wide variety
Barium is often used for spark-plug electrodes and in vacuum tubes as a drying and oxygen -removing agent. As well as fluorescent lamps: impure barium sulfide phosphorescence after exposure to light. Its compounds are used by oil and gas industries to make drilling mud. Drilling mud simplifies drilling through rocks by lubricating the drill.

The most common use of barium is for drilling oil well. Oil is one of the most precious natural source with sky-rocketed price. Therefore, finding an oil well is like finding a well of gold. In order to reach the earth crust where the oil is, the driller needs barium to dig through and make a well of oil.

The barium ore is mined, washed, crushed and is separated from quartz then it is reduced to barium sulfide using carbon. The water-soluble barium sulfide is used to make various compounds of barium such as Barium sulphate, barium nitrate or barium carbonate. These compounds can be used to obtain oxides of barium.
Barium has a melting point of 725°C, a boiling point of 1640°C, and a specific gravity of 3.5 (20°C), with a valence of 2. Barium is a soft metallic element. In its pure form, it is silvery white. The metal oxidizes readily and should be stored under petroleum or other oxygen-free liquids. Barium decomposes in water or alcohol.
Barium has few industrial applications. Historically, it was used as a getter for vacuum tubes and in oxide form as the emissive coating on indirectly heated cathodes. It is a component of YBCO ( high-temperature superconductors) and electroceramics, and is added to steel and cast iron to reduce the size of carbon grains within the microstructure.
1 Abstract. The invention relates to the field of chemical industry, and particularly to a method and a device for extracting barium and barium salt from ore. The method comprises the steps of: washing the ore; roasting the washed ore, obtaining barium sulfide; processing the barium sulfide to obtain barium salt, wherein the barium salt ...
Answer (1 of 2): Barium can be extracted by a simple and sensitive extraction-spectrophotometer method for the purpose of barium is reported. The 18C6-barium-Rose Bengal ternary compound was quantitatively extracted into dichloromethane, and its absorbance was calculated at 565 nm. The calibration table is linear over a barium concentration range of 0.083 - 4.70 µg ml-1.
Barium is a dense alkaline earth metal that occurs naturally in ore deposits and makes up 0.05% of the Earth's crust (Genter 2001). Barium and its compounds may be found in nature or produced industrially for various uses. The largest natural source of barium is barite ore, which is composed largely of barium

Barite that is used as an aggregate in a "heavy" cement is crushed and screened to a uniform size. Most barite is ground to a small, uniform size before it is used as a filler or extender, an addition to industrial products, or a weighting agent in …
Production and processing of barium oxide. Barium oxide can be produced by thermally decomposing barium carbonate, BaCO3 or barium nitrate, Ba (NO3)2. The reactions are as follows: BaCO3 → BaO + CO2. 2Ba (NO3)2 → 2BaO + …
Medical: A high-purity form of barite is used in the gastrointestinal tract where its high density prevents x-ray penetration, and thus is visible on an x-ray. The outline of the gastrointestinal tract thus becomes visible allowing the determination of normal and abnormal anatomy. Construction: Barite can be used as aggregates in high density ...
barite, also called barytes or heavy spar, the most common barium mineral, barium sulfate (BaSO4). Barite occurs in hydrothermal ore veins (particularly those containing lead and silver), in sedimentary rocks such as limestone, in clay deposits formed by the weathering of limestone, in marine deposits, and in cavities in igneous rock. It commonly forms as large tabular crystals, …
