The state of barium in its natural form is solid (not magnetic). Barium is a silvery-white chemical element that belongs to the group of alkaline earth metals. The atomic number of barium is 56. The chemical symbol for barium is Ba. The melting point of barium is 1000 degrees Kelvin or 727.85 degrees Celsius or degrees Celsius.
Barium has a high atomic number and absorbs x-rays strongly. A thin paste of barium sulfate, BaSO 4, and water is is swallowed to coat the alimentary Barium is often used in barium-nickel alloys for spark-plug electrodes and in vacuum tubes as a drying and oxygen-removing agent. Barium oxidizes in air, and it reacts vigorously with water to form the hydroxide, liberating hydrogen.

But because Barium has a different chemistry than Cesium, it is more loosely bound to the resin and can be de-adsorbed with a weakly acidic salt solution containing HCI and NaCI.

Barium-137 Isotope Applications: Barium-137 isotope is used for studies of glass structures through methods of electron paramagnetic resonance (EPR); Barium-137 isotope is used for studies of hyperfine effects; Barium-137 isotope is used for studies of high-temperature superconductors;
In addition to the uses mentioned, barium can also be found in other applications such as: Rubber production Glass TV screens and computer monitors Containers for the storage of radioactive materials White pigment in some paints Production of hydrogen peroxide Magnets Fluorescent lamps Welding
Barium carbonate also has an application that is more appealing than rat poison - it's used in glassmaking to enhance the luster of the glass. And barite is used in paints, bricks, tiles, glass and rubber production; barium nitrate and chlorate give green colors to fireworks and barium titanate was proposed in 2007 to be used in next generation battery technology for electric cars. The most common use of barium is for drilling oil well. Oil is one of the most precious natural source with sky-rocketed price.

Barium metal itself has few uses, but compounds of barium have a wide range of applications. In particular, barium finds use in the brilliant white pigment known as lithopone, which is a mixture of barium sulfate and zinc sulfide.
