The most important use of elemental barium is as a scavenger removing last traces of oxygen and other gases in television and other electronic tubes. Besides, an isotope of barium, ¹³³Ba, is routinely used as a standard source in the calibration of gamma-ray detectors in nuclear physics studies. Barium is an important component of YBCO superconductors. An alloy of barium with nickel is used in spark plug wire. Barium oxide is used in a coating for the electrodes of fluorescent lamps, which facilitates the release of electrons. Barium compounds, and especially barite (BaSO₄), are extremely important to the petroleum industry.

• Barite is used in rubber production and in drilling mud, a weighting agent in drilling new oil wells.^[4]
• Barium sulfate is used as a radiocontrast agent for X-ray imaging of the digestive system ("barium meals" and "barium enemas"). Lithopone, a pigment that contains barium sulfate and zinc sulfide, is a permanent white that has good covering power, and does not darken when exposed to sulfides.
• Barium carbonate is a rat poison and can also be used in making bricks. Unlike the sulfate, the carbonate dissolves in stomach acid, allowing it to be poisonous. Barium carbonate is also used in glassmaking. Being a heavy element, barium increases the refractive index and luster of the glass.
• Barium, commonly as barium nitrate, is used to give green colors in fireworks. The species responsible for the brilliant green is barium monochloride; in the absence of a source of chlorine a yellow or "apple" green is produced instead.
• Barium peroxide can be used as a catalyst to start an aluminothermic reaction when welding rail tracks together. It can also be used in green tracer ammunition and as a bleaching agent.
• Barium titanate was proposed in 2007 to be used in next generation battery technology for electric cars.
• Barium fluoride is used for optics in infrared applications, since it is transparent from about 0.15 to 12 microns (http://www.medbib.com/)
