aria-labelledby="tab1"><img class="image-left" src="https://www.americanelements.com/images_graphics/element-bohr-models/barium-bohr-model.jpg" alt="Barium Bohr Model" width="200" height="200"><p>Similarly to the adjacent element <a href="https://www.americanelements.com/cs.html">cesium</a> within its family of the alkali metals, barium is the heaviest and most reactive of the stable elements in its family, the alkaline earths. The element first gained attention in the early 17th century in Bologna, Italy, when rocks composed of <a href="https://www.americanelements.com/barium-sulfate-7727-43-7">barium sulfate</a> drew alchemists due to their unique ability to emit a phosphorescent red glow for years after being burnt and exposed to sunlight. Barium’s name is derived from the alchemical term for <a href="https://www.americanelements.com/barium-sulfate-7727-43-7">barium sulfate</a> "baryta," which in turn is based on the Greek term <em>barys</em> meaning "heavy" or "dense." Sir Humphrey Davey bestowed the name upon his discovery of the element in 1808 via the electrolysis of molten barium salts, the same technique he used to isolate the other alkali metals. Barium does not occur free in nature due to its high reactivity; it is mostly present as <a href="https://www.americanelements.com/barium-sulfate-7727-43-7">barium sulfate</a> in the mineral barite (also known as barytes or heavy spar), its main commercial source. The element is also found in witherite (<a href="https://www.americanelements.com/barium-carbonate-513-77-9">barium carbonate</a>) to a lesser extent and in the fluorescent blue gemstone benitoite (barium titanium silicate), the official state gemstone of California. Natural barium is a mix of 7 different isotopes and can be produced by either electrolysis of <a href="https://www.americanelements.com/barium-chloride-10361-37-2">barium chloride</a> or the reduction of <a href="https://www.americanelements.com/barium-oxide-1304-28-5">barium oxide</a> with elemental <a href="https://www.americanelements.com/al.html">aluminum</a>.</p><p>Chemically similar to <a href="https://www.americanelements.com/ca.html">calcium</a>, barium is a shiny silver <a href="https://www.americanelements.com/barium-metal-7440-39-3">metal</a> that turns gray as its surface oxidizes in contact with air. The element is extremely electropositive and highly reactive; contact with water and alcohols causes an explosive exothermic reaction, and reactions with nonmetals such as <a href="https://www.americanelements.com/cc.html">carbon</a> and <a href="https://www.americanelements.com/nitrogen.html">nitrogen</a> cause similarly exothermic reactions when heated. Because of its flammability, barium is packaged under mineral oil as a safety precaution. Additionally, soluble barium compounds are all considered extremely poisonous due to the toxicity of the Ba2+ ion and must be handled with care.</p><p>Barium has many different forms with commercially useful properties. As a metal or <a href="https://www.americanelements.com/barium-aluminum-alloy-12253-23-5">alloyed with aluminum</a>, it serves as a “flashed getter” in vacuum tubes to combine with and remove residual <a href="https://www.americanelements.com/oxygen.html">oxygen</a> or moisture; it can also increase the creep resistance of <a href="https://www.americanelements.com/lead-tin-alloy">lead-tin</a> alloys and enhance the structure of <a href="https://www.americanelements.com/aluminum-silicon-alloy">aluminum-silicon</a> alloys. Barium can alloy with other metals such as <a href="https://www.americanelements.com/zn.html">zinc</a>, <a href="https://www.americanelements.com/pb.html">lead</a>, <a href="https://www.americanelements.com/ni.html">nickel</a>, and <a href="https://www.americanelements.com/sn.html">tin</a> to form intermetallic phases and alloys used as bearing alloys, deoxidizers, and (in the form of barium-nickel alloys) the basis for spark plug wires. Barium compounds such as <a href="https://www.americanelements.com/barium-carbonate-513-77-9">carbonates</a>, <a href="https://www.americanelements.com/barium-chloride-10361-37-2">chlorides</a>, <a href="https://www.americanelements.com/barium-oxide-1304-28-5">oxides</a>, <a href="https://www.americanelements.com/barium-hydroxide-17194-00-2">hydroxides</a>, and <a href="https://www.americanelements.com/barium-peroxide-1304-29-6">peroxides</a> are used as bleaching agents, desiccants, water softeners, components of glass and ceramics, additives to oil drilling fluids, green colorings for fireworks, and rat poisons; some other applications include purification of solutions and calibration of pH equipment. <a href="https://www.americanelements.com/barium-sulfate-7727-43-7">Barium sulfate</a> is uniquely insoluble in water and thus nontoxic, allowing it to be used as a radiopaque contrast media for X-ray and CAT scan imaging of the gastrointestinal tract in high purity form. The compound either by itself or in combination with <a href="https://www.americanelements.com/zinc-sulfide-1314-98-3">zinc sulfide</a> (a material known as lithopone) is also used as a white pigment in paints, ink, and coatings in addition to a filler for rubbers and plastics.</p><p>Some crystalline ceramic forms of barium possess unusual properties that give them specialized high technology applications. <a href="https://www.americanelements.com/yttrium-barium-copper-oxide-107539-20-8">Yttrium barium copper oxide</a> (YBCO) is a well-known high-temperature superconductor, the first material ever to be discovered that exhibits superconductivity above the temperature of liquid nitrogen (77 K). Magnetic strips of credit card and data storage devices utilize <a href="https://www.americanelements.com/barium-ferrite-12047-11-9">barium ferrite</a>, a magnetic material that can take on a complex ferromagnetic fluid phase at room temperature. <a href="https://www.americanelements.com/barium-titanate-iv-12047-27-7">Barium titanate</a> and <a href="https://www.americanelements.com/barium-zirconate-12009-21-1">barium zirconate</a> (when combined, known as barium zirconate titanate or BZT) are piezoelectric, ferroelectric perovskite crystals that can function as dielectric materials in capacitors, electrolytes in solid oxide fuel cells, and nonlinear optical crystals; <a href="https://www.americanelements.com/barium-fluoride-7787-32-8">barium fluoride</a> is another common optical material used in lenses, windows, and scintillators due to its wide transparency in the ultraviolet and infrared spectra.</p></div></div> </div> </div> <div id="tab-products" class="tab-body paragraph paragraph--type--product paragraph--view-mode--default"> <div
