Characteristic
Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.
Phase at STP：solid
Appearance：silvery gray; with a pale yellow tint
Melting point：1000 K (727 °C, 1341 °F)
Boiling point：2118 K (1845 °C, 3353 °F)
Density (near r.t.)：3.51 g/cm3
when liquid (at m.p.)：3.338 g/cm3
Heat of fusion：7.12 kJ/mol
Heat of vaporization：142 kJ/mol
Molar heat capacity：28.07 J/(mol·K)
Due to dangerous materials, the delivery date cannot be fully guaranteed (maybe extended). Don't hesitate to contact us for details.
Application
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. Barium compounds are added to fireworks to impart a green color. Barium sulfate is used as an insoluble additive to oil well drilling fluid, as well as in a purer form, as X-ray radiocontrast agents for imaging the human gastrointestinal tract. The soluble barium ion and soluble compounds are poisonous, and have been used as rodenticides.
